WRG controller @@&name@@

 

Heat recovery controller for cable distribution cabinet or circulating heat exchanger, etc., normally influences the supply air temperature. This does NOT switch to active mode, but is activated by a preceding controller if need be (e.g. preheater controller).

 

If there is a failure of the heat exchanger, the signal is issued with 0%. The frost safety function however overrides.

 

If there is a danger of frost in the preheater (detected via function "@@&ref@@"), a predefined signal is issued.

 

The outside air temperature is compared with the ambient and/or exhaust air temperature and the favourable air according to heat or cold is used.
