Johnson Controls SABROE WHC 2.1 Installation And Operating Manual page 7

Design and function
• The WHC controller receives a start signal from the compressor. The start signal
changes the set point for the water temperature, so it is possible to have a higher water
temperature at standstill (heating) and a lower temperature in operation (cooling).
• The WHC controller only allows the compressor to start and run if the water flow (
Fig. 1, pos. FS001) and temperature (Fig. 1, pos. TC001) is OK. The minimum operat-
ing temperature is 35°C and maximum is 85°C.
The system has a total output of 1100 W.
