Load
The Setpoint Control 162 is designed to support six different
applications. The items shown in the VIEW and ADJUST
Menu change depending on the Application Mode.
Set the application mode as follows:
1) On / Off Setpoint
2) Hot Tub
3) Indirect DHW Tank
4) PWM Setpoint
5) Floor
6) Pool
Application Overview
The VIEW and ADJUST menus list which of the six application
items are visible based upon the mode column.
The TIME, SCHD (Schedule) and MISC (Miscellaneous)
menus are the same for the six application modes.
Applications: On / Off Differential
Mode 1 Setpoint (On / Off)
Mode 2 Hot Tub
Mode 3 DHW Tank
Relay 1 On / Off Differential Operation
The On / Off Differential operates by centering a differential
range around the target setpoint temperature. On / Off
differentials are best suited to heating or cooling loads
that quickly change temperature.
Heating Operation
When heating, the setpoint control turns on Relay 1 when
the temperature falls to 1/2 of the differential below the
setpoint and turns off Relay 1 once the temperature reaches
1/2 of the differential above the setpoint.

Cooling Operation
When cooling, the setpoint control turns on Relay 1 when
the temperature rises to 1/2 of the differential above the
setpoint and turns off Relay 1 once the temperature falls
1/2 of the differential below the setpoint.
