  • Operation/external diagnostics - when any thermostat calls for heat, the appropriate zone valve is energized and the yellow light goes on
  • When the zone valve is fully open, the red light goes on and energizes the end switch relay
  • The green light should always be on, indicating that power is connected
  • Priority operation - when zone 4 is switched to the priority setting and is actuated, all other zones will stop operation until zone 4 is satisfied
