Characteristics
CMT727 RF Wireless Thermostat for automatic temperature control over time in heating installations in villas or apartments.
Can control: wall panels, burners, circulation pumps, motorized valve valves and electric heating systems.
Display: liquid crystal display;
Working modes: manual, automatic, holiday, wake (anti-freeze);
Control mode P + I (proportional + integral) to ensure a controlled flow temperature increase in the flow circuit, avoiding sudden pipe expansion and noise in the system, the flow variation in the flow and ambient circuit has a low value
7-day programming, 4 independent temperature change times per day.
Time intervals: at choice, in 10-minute increments;
Holiday key, reduces temperature over a scheduled period of 1 to 99 days;
Manual temperature override programmed to the next switching point;
The temperature display key is currently displaying the ambient temperature.
The EEPROM memory keeps the user-set program infinite.
The OFF key provides adjustable anti-freeze protection at a minimum of 5 ° C.
Displays: ambient temperature, boiler on, clock, day, working mode, battery consumed.
Installer settings, working mode to adjust the following parameters:
Optimization (active or inactive) ensures that the desired temperature is reached at the scheduled time by shutting down or starting up the plant in advance, while memorizing the required time.
Time display in 24h or 12h AM / PM, automatic summer / winter switching;
Adjusting the minimum and maximum limits of the temperature adjustment range;
Adjustable propensity band from 1.5 to 3 ° C;
+/- 1 ... 3 ° C offset of the temperature read when installed in an inappropriate place;
