Wired digital camera thermostat Q3

Description

Wired digital camera thermostat Q3

for controlling a heater or air conditioner

The Computherm Q3 room thermostat is compatible with most central heating boilers sold in Romania, regardless of the control voltage (24 V or 230 V).
The digital display allows more accurate temperature measurement and adjustment than mechanical thermostats.
The thermostat controls the heater or air conditioner so that the ambient temperature is kept constant, at the value you want. The high precision of the thermostat ensures COMFORT in your home or office, as well as ECONOMY on energy costs.
requires a wired electrical connection to the boiler
Switching sensitivity is the difference between the set temperature and the temperature at which the thermostat switches on / off the boiler. The sensitivity of the thermostat is ± 0.2 ° C.
The display accuracy is ± 0.5 ° C.
The display is easy to read and shows both the set temperature and the room temperature.
The output for the electrical connections is made on the tilting contacts (NO - normally open, NC - normally closed and COM - common) without the electrical potential of a relay. The relay contacts can switch 24 Vdc or VAC, up to 230Vac, 50 Hz and a current of 8 A resistive, or 2 A inductive.
The antifreeze function ensures a minimum of 7 ° C.
Pump anti-lock function. In order to prevent the pump from stalling at 0 and 00 minutes, the thermostat commands the boiler to start for one minute. The command is given only if the thermostat has not given a start command for 24 hours.
