Programmable thermostat Power supply: Working temperature: Thermostat is designed to control the ARWE, A3RWE and AREX fan speed controllers and the EC motors using a 0-10VDC signal. It has the option of 4-zone 7-day programming, which allows to set the desired temperature in 4 different time zones for each day of the week separately. In addition, thermostat has the ability to automatically turn on and off at a specified time. The choice of one of 4 operating modes allows to use the device in heating, cooling, ventilation or mixed systems. The system is equipped with contacts controlling hot and cold water valves.
