Calculations,&WaterFlowSelection
Source Water Flow SelectionProper flow rate is crucial for reliable operation of geothermal heat pumps. the performance data shows three flow rates for each entering water temperature (ESt column). the general “rule of thumb” when selecting flow rates is the following:
top flow rate: open loop systems (1.5 to 2.0 gpm per ton)Middle flow rate: Minimum closed loop system flow rate (2.25 to 2.50 gpm/ton)Bottom flow rate: Nominal (optimum) closed loop system flow rate (3.0 gpm/ton)
Although the “rule of thumb” is adequate in most areas of North America, it is important to consider the application type before applying this “rule of thumb.” Antifreeze is generally required for all closed loop (geothermal) applications. Extreme Southern u.S. locations are the only exception. open loop (well water) systems cannot use antifreeze, and must have enough flow rate in order to avoid freezing conditions at the Leaving Source Water temperature (LWt) connection.
Calculations must be made for all systems without antifreeze to deter-mine if the top flow rate is adequate to prevent LWt at or near freezing conditions. the following steps should taken in making this calculation:
Determine minimum ESt based upon your geographical area.Go to the performance data table for the heat pump model selected and look up the the Heat of Extraction (HE) at the “rule of thumb” water flow rate (GPM) and at the design Entering Load temperature (ELt).
Calculate the temperature difference (tD) based upon the HE and GPM of the model.tD = HE / (GPM x 500).Calculate the LWt.LWt = ESt - tD.
If the LWt is below 35-38°F, there is potential for freezing conditions if the flow rate or water temperature is less than ideal conditions, and the flow rate must be increased.
Example 1:ESt = 50°F, ELt = 95°F.Model rWt034, heating. Flow rate = 5 GPM. HE = 30,100 Btuh.tD = 30,100 / (5 x 500) = 12.0°FLWt = 50 - 12.0 = 38.0°FWater flow rate should be adequate under these conditions.
Example 2:ESt = 40°F, ELt = 95°F.Model rWt036, heating. Flow rate = 5 GPM. HE = 25,700 Btuh.tD = 25,700 / (5 x 500) = 10.3°FLWt = 40 - 10.3 = 29.7°FWater flow rate must be increased.
Heating Cooling
LWt = ESt - HE GPM x 500*
LWt = ESt + Hr GPM x 500*
HE = 500* x GPM x (EWt - LWt) Hr = 500* x GPM x (LWt - EWt)
*500 = Constant factor for pure water. Brine should be 485.
Heating & Cooling Calculations
CoP = Coefficient of Performance = Btu output / Btu Input Hr = total Heat of rejection, Btu/hr
DH = Desuperheater Capacity, Btu/hr KW = total Power unit Input, Kilowatts
EEr = Energy Efficiency ratio = Btu output/Watts input LWt = Leaving Source Water temperature, Fahrenheit
ESt = Entering Source Water temperature, Fahrenheit LLt = Leaving Load Water temperature, Fahrenheit
ELt = Entering Load Water temperature, Fahrenheit tC = total Cooling Capacity, Btu/hr
GPM = Water Flow, Gallons Per Minute HC = Heating Capacity, Btu/hr
HE = total Heat of Extraction, Btu/hr WPD = Water Pressure Drop, PSI & Feet of Water
Glossary
Notes:1. Desuperheater Capacity is based upon 0.4 GPM Flow per nominal ton at 90°F entering hot water temperature.2. Extrapolation data down to 25°F for heating and interpolation between ESt & GPM data is permissible.3. EWt (Entering Water temperature) is also called ESt (Entering Source temperature).4. Load flow rate is the same as the source flow rate at each of the three flow selections.

Because the water-to-water machines have become so popular for providing heated water for a multitude of uses, we’ve provided the above chart for reference.
The obvious correlation is that the warmer the Source Entering Water Temperature, the hotter the Load Leaving Water Temperature can be, to a point. R410A can only handle up to about 125°F Load Leaving Water Temperature before putting the compressor at risk.
Actual usage, and choices of heat distribution devices need to follow the acceptable operating conditions presented in the chart. If a question arises, please consult the Technical Services Department.

Buffer Tanks
Virtually all water-to-water heat pumps used for hydronic applications require a buffer tank to prevent equipment short cycling, and to allow different flow rates through the water-to-water unit than through the hydronic delivery system. The following are considerations for buffer tank sizing.
• The size of the buffer tank should be determined based upon the predominant use of the water-to-water equipment (heating or cooling.
• The size of the buffer tank is based upon the lowest operating stage of the equipment. For example, a water-to-water heat pump with a two-stage compressor or two compressors may be sized for first stage capacity, reducing the size of the tank (as long as a two-stage aquastat is used).
• Pressurized buffer tanks are sized differently than non-pressurized tanks (see guidelines listed below).
Pressurized buffer tanks for predominately heating applications should be sized at one (1) U.S. gallon per 1,000 Btuh of heating capacity (10 gallons per ton may also be used) at the maximum entering source water temperature (EST) and the minimum entering load water temperature (ELT), the point at chich the water-to-water unit has the highest heating capacity, usually 50-70°F EST and 80-90°F ELT.
For predominately cooling applications, pressurized buffer tanks should be sized at one (1) U.S. gallon per 1,000 Btuh of cooling capacity (10 U.S. gallons per ton may also be used) at the minimum EST and the maximum ELT, the point at which the water-to-water unit has the highest cooling capacity, usually 50-70°F ESt and 50-60°F ELT.
Select the size of the tank based upon the larger on the calculations (heating or cooling).
Non-pressurized buffer tanks must also be sized based upon predominate use (heating or cooling) and based upon the lowest capacity stage. Requirements for storage are less according to the manufacturer of the HSS series non-pressurized buffer tank. Using the same conditions for maximum heating and cooling capacity mentioned above, on-pressurized buffer tanks require 6 U.S. gallons per ton.

Controls
MiCrOPrOCeSSOr FeATUreS AND OPerATiON Roth’s geothermal heat pump controls provide a unique modular approach for controlling heat pump operation. The control system uses one, two, or three printed circuit boards, depending upon the features of a particular unit. This approach simplifies installation and troubleshooting, and also eliminates features that are not applicable for some units.
A microprocessor-based printed circuit board controls the inputs to the unit as well as outputs for status mode, faults, and diagnostics. A status LED and an LED for each fault is provided for diagnostics.
Removable low voltage terminal strips provide all necessary terminals for field connections. Not only are the thermostat inputs included, but there are also removable terminal strips for all of the accessory wiring for ease of installation and troubleshooting. Startup/random StartThe unit will not operate until all the inputs and safety controls are checked for normal conditions. At first power-up, the compressor is energized after a five minute delay. In addition, a zero to sixty second random start delay is added at first power-up to avoid multiple units from being energized at the same time.
Short Cycle Protection A built-in five minute anti-short cycle timer provides short cycle protection of the compressor.
Component Sequencing DelaysComponents are sequenced and delayed for optimum space conditioning performance and to make any startup noise less noticeable.
Test Mode The microprocessor control allows the technician to shorten most timing delays for faster diagnostics by changing the position of a jumper located on the lockout board.
Water Solenoid Valve Connections Two accessory relay outputs at the terminal strip provide a field connection for two types of water solenoid valves, a standard 24VAC solenoid valve, or a 24VAC solenoid valve with an end switch. Additional field wiring is no longer required for operation of the end switch.
Loop Pump Circuit Breakers (Single Compressor Units)The loop pump(s) and desuperheater pump are protected by control box mounted circuit breakers for easy wiring of pumps during installation. Circuit breakers eliminate the need to replace fuses.
Safety Controls The control receives separate signals for high pressure, low pressure, low water flow, and condensate overflow faults. Upon a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is suspended (see Fault Retry below), and the appropriate LED flashes. Once the unit is locked out (see Fault Retry below), an output (terminal “L”) is made available to a fault LED at the thermostat (water-to-water unit has fault LED on the corner post).
Low Pressure: If the low pressure switch is open for 30 continuous seconds, the compressor operation will be interrupted, and the control will go into fault retry mode. At startup, the low pressure switch is not monitored for 90 seconds to avoid nuisance faults.
High Pressure: If the high pressure switch opens, the compressor operation will be interrupted, and the control will go into fault retry mode. There is no delay from the time the switch opens and the board goes into fault retry mode. There is also no delay of switch monitoring at startup.
Flow Switch: If the flow switch is open for 30 continuous seconds, the compressor operation will be interrupted, and the control will go into fault retry mode. At startup, the flow switch is not monitored for 30 seconds to avoid nuisance faults.

FAULT reTry All faults are retried twice before finally locking the unit out. The fault retry feature is designed to prevent nuisance service calls. There is an anti-short cycle period between fault retries. On the third fault, the board will go into lockout mode.
Over/Under Voltage Shutdown The lockout board protects the compressor from operating when an over/under voltage condition exists. The control monitors secondary voltage (24VAC) to determine if an over/under voltage condition is occurring on the primary side of the transformer. For example, if the secondary voltage is 19 VAC, the primary voltage for a 240V unit would be approximately 190V, which is below the minimum voltage (197V) recommended by the compressor manufacturer. This feature is self-resetting. If the voltage comes back within range, normal operation is restored. Therefore, over/under voltage is not a lockout.
Under voltage (18 VAC) causes the compressor to disengage and restart when the voltage
returns to 20 VAC. Over voltage (31 VAC) causes the compressor to disengage and restart when the voltage returns to 29 VAC. During an over or under voltage condition, all five fault LEDs will blink (HP + LP + FS + CO + Status). When voltage returns to normal operation, the four fault LED’s will stop blinking, but the status LED will continue to flash. While the board LEDs are flashing, the thermostat fault light will be illuminated.
intelligent reset If the thermostat is powered off and back on (soft reset), the board will reset, but the last fault will be stored in memory for ease of troubleshooting. If power is interrupted to the board, the fault memory will be cleared.
Diagnostics The lockout board includes five LEDs (status, high pressure, low pressure, low water flow, condensate overflow) for fast and simple control board diagnosis. Below is a table showing LED function.

Notes:1. Looking at the board when the LEDs are on the right hand side2. If all five lights are flashing, the fault is over/under voltage3. only the light associated with the particular fault/lockout will be on or flashing.
For example, if a high pressure lockout has occurred, the top green light will be on. the orange, red, and yellow lights will be off

Controls
Hot Water Pump Control Controls for high water temperature and low compressor discharge line temperature prevent the hot water (desuperheater) pump from operating when the leaving water temperature is above 130°F, or when the compressor discharge line is too cool to provide adequate water heating.
Lockout Board Jumper SelectionThe lockout board includes three jumpers for field selection of various board features.
Water Solenoid Valve Delay (WSD): When the WSD jumper is installed, the “A” terminal is energized when the compressor is energized. When the jumper is removed, the “A” terminal is energized 10 seconds after the compressor. If using the Taco water solenoid valve (or a valve with an end switch), the unit terminal strip includes a means for connecting a valve of this type. The WSD jumper should be installed. If using a slow opening valve that does not have an end switch, the jumper should be removed.
Test Mode (TEST): When the TEST jumper is installed, the board operates in the normal mode. When the jumper is removed, the board operates in test mode, which speeds up all delays for easier troubleshooting. When service is complete, the jumper must be re-installed in order to make sure that the unit operates with normal sequencing delays.
Over/Under Voltage Disable (O/V): When the O/V jumper is installed, the over/under voltage feature is active. When the jumper is removed, the over/under voltage feature is disabled. On rare occasions, variations in voltage will be outside the range of the over/under voltage feature, which may require removal of the jumper. However, removal of the jumper could cause the unit to run under adverse conditions, and therefore should not be removed without contacting technical services. An over/under voltage condition could cause premature component failure or damage to the unit controls. Any condition that would cause
this fault must be thoroughly investigated before taking any action regarding the jumper removal. Likely causes of an over/under voltage condition include power company transformer selection, insufficient entrance wire sizing, defective breaker panel, incorrect transformer tap (unit control box), or other power-related issues.
