TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING RULES: Use the unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.

Before installing, servicing or troubleshooting the transformer/re-lay package, switch power off at service panel and lock service panel to prevent power from being switched on accidentally.

WARNING

More than one disconnect switch may be required to de-energize the equipment for servicing.

Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction codes and standards.

When cutting or drilling into wall or ceiling, do not damage elec-trical wiring and other hidden utilities.

NEVER place a switch where it can be reached from a tub or shower.

Intended for use with 24VAC Class 2 power supplies only.

Do not connect loads that exceed the timer’s switch rating.

Confirm sufficient 24VAC power is available to operate the timer and the connected loads.

NOTE: There is a wire on the TC7D that connects

terminal 1 to terminal 5. You must cut this wire to eliminate voltage to terminal 5.

In this example, the timer turns the Energy Recovery Ventilator (ERV) on at High speed when the timer dictates it is an occupied time.

In this example, the ERV does not run while unoccupied, set by timer. During occupancy, ERV runs at variable Speed. CO2 Controller sets speed based on CO2 levels. Remove the potentiometer(s) by cutting the wires at the potentiometer. Cap the orange and purple wires from the potentiometer with wire nuts. EV450 Circuit Board shown with one potentiometer. HE1X and HE1.5 Circuit Board has two potentiometers and the cut wires can be wired in parallel back to the CO2 Controller.

About RenewAireFor over 30 years, RenewAire has been a pioneer in enhancing indoor air quality (IAQ) in commercial and residential buildings of every size.This is achieved while maximizing sustainability through our fifth-generation, static-plate, enthalpic-core Energy Recovery Ventilators (ERVs) that optimize energy efficiency, lower capital costs via load reduction and decrease operational expenses by minimizing equipment needs, resulting in significant energy savings. Our ERVs are competitively priced, simple to install, easy to use and maintain and have a quick payback. They also enjoy the industry’s best warranty with the lowest claims due to long-term reliability derived from innovative design practices, expert workmanship and Quick Response Manufacturing (QRM).

As the pioneer of static-plate core technology in North America, RenewAire is the largest ERV producer in the USA. We’re committed to sustainable manufacturing and lessening our environmental footprint, and to that end our Waunakee, WI plant is 100% powered by wind turbines. The facility is also one of the few buildings worldwide to be LEED and Green Globes certified, as well as having achieved ENERGY STAR Building status. In 2010, RenewAire joined the Soler & Palau (S&P) Ventilation Group in order to provide direct access to the latest in energy-efficient air-moving technologies.
