Self-learning Room

Temperature Controller

REV12

5 operating modes, 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 2 heating periods, continuously comfort mode, con-

tinuously economy mode, frost protection with one 24-hour operating mode

and one heating period

• In automatic mode, one temperature setpoint can be adjusted for each heating

period

Use

For the control of the room temperature in:

• Apartments, single-family or holiday houses

• Offices, individual rooms, consulting rooms or commercially used spaces

For the 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

PAGE 5
Switching program The switching program is used as the 24-hour program. It is also possible to select one of the continuous operating modes with which the switching program is not used. When a heating period is programmed, 2 different switching patterns are available. It is possible to select one or 2 heating periods. For each heating period, the start time, end time and comfort temperature setpoint are to be entered.
PAGE 6
Control The REV12 is a 2-position controller providing PID mode. The room temperature is controlled through the cyclic switching of an actuating device. The controller generates the positioning signals depending on the deviation of the setpoint from the actual value acquired by the built-in temperature sensor. The rate of response to the deviation depends on the selected control algorithm.
PAGE 7
Notes Engineering • The room temperature controller should be fitted in the main living room • The place of installation should be chosen such that the sensor can capture the room temperature as accurately as possible, without being affected by direct solar radiation or other heating or cooling sources • Mounting height is approximately 1.
