GreenMAX Relay Panel - Override for daylight harvesting

[Surfinbear]

Hello
We have a project that is using an 8-relay GreenMAX panel with Sapphire and ODC0P-00W. Six of the relays(RELAY-1CB) are doing on/off daylight harvesting in an atrium area. The atrium is sometimes used for picture taking so the customer now wants an override switch to force the lights on when the photocell has turned the lights off. Is there a way to do this?

Leviton's GreenMAX Relay Panel key switch, RDGSW-1KS can be used for exactly this function!

Hi,

Are you able to provide more details on how that would work?

The current setup we have just to give a little more info is the following:
- Photocell is programmed as a trigger point photocell
- CB relays are using B12, ON, Photocell off
- Also have a sapphire connected to the system that is able to turn on and off the lights if the photocell is not turning the relays off. However when it is too bright in the area and the photocell is turning the the lights off the sapphire will not override.

Thoughts? Suggestions?

There are no provisions in the programming of the GM panel or Sapphire to override a photocell. the only way to accomplish that is to disable the photocell by cutting the 24+ power supply.

You can do this in two ways:
1) No programming is needed, if you add a key switch and run the 24+ wire going to the photocell and when needed turn it the switch off the lights should go to full.

2) If you have a spare relay you can run the 24+ in and out the relay and control the relay with the sapphire.
