Siemens REV24.. room temperature controller CE1N2205en
Building Technologies 24.04.2008
The REV24… is a two-position controller with PID control. The room temperature is
controlled through cyclic switching of an actuating unit.
DIP switches 4 ON and 5 ON: PID self-learning
Adaptive control for all applications.
DIP switches 4 ON and 5 OFF: PID 6
Fast controlled system for applications in locations with
large temperature deviations.
DIP switches 4 OFF and 5 ON: PID 12
Normal controlled system for applications in locations with
normal temperature deviations.
DIP switches 4 OFF and 5 OFF: 2-point
For complex controlled systems, simple two-position controller with
0.5 °C switching difference (factory setting).
Press the DIP switch reset button to save the settings.
Only applicable with controlled circulating pump or valve!
This function protects the pump or valve during extended OFF periods against possible
seizure caused by liming. Periodic pump run is activated every 24 hours at 12 p.m. for
three minutes (symbol is displayed during active pump run).
DIP switch ON: Pump run On.
DIP switch OFF: Pump run On (factory setting).
Press the DIP switch reset button to save the settings.
Optimization advances the switch-on point P.1 to ensure that the selected setpoint is
reached at the desired time. The setting depends on the controlled system, i.e., on heat
transmission (piping system, radiators), building dynamics (building mass, insulation),
and heat output (boiler capacity, flow temperature).
DIP switches 7 ON and 8 ON: 1 h/°C For slow controlled systems.
DIP switches 7 ON and 8 OFF: ¼ h/°C For fast controlled systems.
DIP switches 7 OFF and 8 ON: ½ h/°C For medium controlled systems.
DIP switches 7 OFF and 8 OFF: OFF Off, no effect (factory setting).
Press the DIP switch reset button to save the settings.
