Hardware architecture
TRACER CH532 offers customer the possibility to use inputs or outputs in order to:
-use an external water setpoint reset using an analog input (refer to figure 3)
-use an auxiliary setpoint
-connect a remote on/off of the unit or a circuit
-reset faults
-connect a remote Cooling/Heating switch
-return a circuit fault
Note: External water setpoint
Based on a external signal input, it will be possible to offset the active setpoint from 0°C to 20°C. This function can be used in conjunction with the automatic setpoint reset function.
