Client needs to have either the exhaust fan or a ceiling heater controlled
The ATX LED system can support powering an AC 120V ceiling heater by pairing it with a 12V relay.
The Relay
The DC to AC relay can be found here: https://www.amazon.com/dp/B000LESCI2/
This device bolts thru the side of a standard junction box. It is possible connect this such that no wire nut junctions occur such that 120vac and 12v vdc junctions are in the same junction box - meeting NEC code
Wiring
The ATX LED DR2C / Bath / DR2F would be wired with the Fan output connected to a Single Pole Dual Throw (SPDT) switch - often referred to as a "3-Way" switch.
The SPDT Switch would have it's two outputs connected as follow:
- Positive leg of the 12v DC FAN
- Positive leg of the RIBU1C
The negative legs of the Exhaust Fan and the RIBU1C would both tie back to the negative connector on the back of the switch.
When the DR2C / Bath / DR2F turns the "fan" ON - either the Fan or the Heater goes on, depending on the position of the SPDT (3-way) switch.
Finally, the RIBU1C will be connected via 120vac to the heater as per its manual.
Operation
To switch from fan to heater mode, simply switch the SPDT to select.
The heater or the fan will both operate in the same manner as the fan would typically operate as per the manual of the switch in use.
For more information on fan mode operation, please refer to the manual of your switch:
