Hello, I need the model number of the Sunvic thermostat, and a close up *well lit* and well focused photo of it.

Also I need the model number of the Honeywell cylinder thermostat.

USe the 'attach files' link to the left of your send button to attach the photo.

You will need a multi meter to run some tests.
