Honeywell ST699

Product Information

The thermostat cable will be between terminal 4 on new programmer and brown of CH two port valve, connect brown of the CH valve directly to terminal 4 so it excludes the now redundant thermostat cable. The front control unit has spring loaded contacts to the base plate, so you don't even need to do any rewiring.Yes, there are cheaper, more up to date timer controls available but what you are paying for is ease of replacement.
