Operation

 

 

5.2.5.1Reduced operation

During reduced operation, you can select between two operating modes.

Factory setting

ECO

Setting range

ECO, RED

Set values

RED (lowering operation)

 

The heating circuit pump of the direct heating circuit continues

 

functioning during reduced operation (see 5.2.3.2 Time program,

 

pg. 73). The flow temperature is determined based on the lowered

 

room temperature from the associated reduced heating curve.

 

The set maximum temperature is not undershot.

Application

Building with minimal insulation values and high cooling loss.

 

ECO (switch-off operation)

 

During reduced operation, the direct heating circuit is switched off

 

completely with outside temperatures above the set frost-

 

protection limit. The maximum heat generator temperature is not

 

functional. The heating circuit pump is switched off after a delay to

 

avoid safety deactivation by reheating the heat generator (pump

 

follow-up).

 

If the outside temperature is or becomes lower than the specified

 

outside temperature frost-protection limit, the controller switches

 

from deactivated (deactivation mode) to lowered lowering

 

operation and controls the heating circuit temperature based on

 

the set lowering curve taking the set minimum heat generator

 

specification into account.

Application

Building with high insulation values (full heating protection).

NOTE

The mode set here also applies for the ABSENT and RED.

 

HEATING operating modes.
