THERMOPROGRAMTH124The TH124 THERMOPROGRAM programmablethermostat has been designed to guarantee idealtemperature conditions at all times during the day.Installation takes only minutes. The thermostat canbe connected to the heating/cooling installationsimply by means of two wires.Three alkaline LR6 1.5 V penlight AAA batteries areused to power THERMOPROGRAM for over ayear.It can be programmed easily using the sliders; thelarge display shows the time and ambient temper-ature together with all programmed data.The thermal differential is adjustable from 0.1 °C to0.9°C

The THERMOPROGRAM can control both heat-ing and air-conditioning systems, and can beinstalled as a replacement for a previous on/offprogrammable thermostat.

9 - HOLIDAY PROGRAMMEIf a fixed temperature is required for a few hoursor a few days (for example, to maintain a com-fortable temperature during unforeseen visits orto set a frost protection temperature during win-ter absence) it is possible to activate the HOLI-DAY PROGRAMME in timed MANUAL mode.Once the desired duration has been set, thedevice starts a countdown. When it reacheszero, the unit switches from MANUAL to AUTO-MATIC mode, resuming the set programme.
