Self-learning Room
Temperature Controller
5 operating modes, heating / cooling functions and menu selection via roller selector
• Mains-independent room temperature controller
• Straightforward, self-explanatory menu selection via roller selector
• Self-learning 2-position controller providing PID mode (patented)
• Choice of operating modes:
automatic with maximum 3 heating or cooling periods, continuously comfort
mode, continuously economy mode, frost protection with one 24-hour operat-
ing mode and one heating or cooling period
• In automatic mode, one temperature setpoint can be adjusted for each heating
or cooling period
• Control of cooling equipment
For the control of the room temperature in:
• Apartments, single-family or holiday houses
• Offices, individual rooms, consulting rooms or commercially used spaces
For control of the following pieces of equipment:
• Solenoid valves of instantaneous water heaters
• Solenoid valves of atmospheric gas burners
• Forced draft gas or oil burners
• Circulating pumps in heating systems, zone valves
• Electric direct heating systems or fans of electric storage heaters
• Thermic actuators
• Cooling and refrigeration equipment

  • Page 7 Starting point of optimum start control Control The REV23 is a 2-position controller providing PID mode. The room temperature is controlled through the cycling switching of an actuating device. The controller generates the positioning signals depending on the deviation of the ad- justable setpoint from the actual value acquired by the built-in temperature sensor.
