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.
