NOTES:
1) Refer to the I&O to determine correct valve orientation and actuator wiring.
2) 120 VAC supplying the RTC may or may not be separate from the burner/boiler circuit.
3) Heat demand can be any electrical signal consisting of 24 – 240 VAC.
4) Use isolation relays for circulators greater than 1/3 HP. Use motor starters for 3 phase circulators.
5) In COLD STANDBY applications, set the “OPEN DELAY” variable to 30 seconds.
