Hi, All. New member here. I'm installing an Elk M1G system for security and lighting. Lighting control is via UPB and a little bit of legacy X10. I want to control my two attic gable-end fans. The fans are on in-line thermostats to cut them off when the attic temperature drops below a setpoint. I also want to have an override that shuts them off at a specific time (say 11:00 PM) on hot summer nights to keep the noise in the house down. I think the fans are rated at about 3 amps each (need to verify this). I'm considering two options:
Thoughts? Thanks in advance.

- A UPB fixture module that can be triggered by the Elk M1G at 11:00 PM
- Use one of the the Elk Programmable Outputs (J16) to drive a relay.
- Are there other alternative approaches you would recommend?
- Can I mount the UPB fixture module in the attic? I'm not sure what daytime peak attic temp is -- probably 130F? I'm sure it would be better to put it in the house conditioned environment, but interior space is at a premium.
- If I choose to use a relay off a Programmable Output, would I use a Elk 924 DPDT relay or an Elk Heavy Duty Contactor/Relay? I know the 60A HD Contactor/Relay is way overkill for this application, but I like the idea of "real" screw terminals for the 14 gauge Romex wire. The relay terminals on the 924 relay meet my current requirements, but the terminal screws don't seem up to connecting 14 gauge Romex.
Thoughts? Thanks in advance.
