location for the wiring of heating and cooling systems. Follow the
instructions below for proper usage:
Jumper Functions
The device comes with jumper functions that allow you to
configure different settings. Follow the instructions below:
- Jumper Function 1 – Change Over: Set the jumper to ON if the
signal is coming from Zone 1 CO Input, or OFF if the signal is
coming from CO Input. - Jumper Function 2 – Pump Delay: Set the jumper to ON if you
want the pump to start after 5 minutes, or OFF if you want the pump
to start with thermostat request. - Jumper Function 3 – Pump Exercise Function: Set the jumper to
ON if you want the pump to run at least 5 minutes every 24 hours,
or OFF if you want the function disabled.
Electrical Connection
