Example Connections, HVAC

1. HVAC Unit

Standard A/C units and HVAC heating and cooling control units that are operated by low-voltage (24Vac)

control signals can be connected to the RD8i for programmable control. Land each control signal on a sepa-

rate relay contact, then jumper the Rc (red) 24Vac power lead from the FCU to each terminal. When any of

the relays are energized, the 24Vac will be switched to the control signal to activate the FCU.

2. Dehumidifier Unit

24VAC humidifier/dehumidifier control signals may be operated by dry contact. Simply connect the low

voltage control signals to any contact. When the contact is activated, the control signal is connected and

activates the humdity equipment. Check the equipment cycles properly by connecting the control wires

together to verify the equipment turns on as expected before wiring to a relay contact.
