Functions
For details refer to the “CLC” description of functions at the beginning of this section (CA2A3815E00). Application CLC02 includes the following functions:
Function Brief description Proportional heating and cooling – PID control sequence – Two proportional control sequences, heating and cooling – Control of thermic valve actuators (AC 24 V, PWM) – Valve exercising feature
See CA2A3815E00 6.1 6.4 6.6
Dew point sensor
– Dew point sensor to prevent condensation formation
6.5
Operating modes
2, 3
Setpoint reset
– Comfort, Stand-by, Economy and Building protection – Change of operating mode via /Auto switch on room unit, occupancy sensor, window contact or central command – Locally via room unit or via central command
Temperature measurement
– Via room unit or passive temperature sensor
General functions
