I installed two Wyze thermostats to a 2 wire 2 zone boiler. The first install went just fine using Rc and C for power and Rh and W1 for trigger. I mounted the plate with the level at the top.
Correct layout on base plate
Rc Y1 Y2 o/b G
Rh W1 W2 * C
The second thermostat install should be even quicker I thought. I placed all the wires as I had done on the first. The Wyze thermostat booted up but would not trigger the boiler. I thought I had messed up some wiring on the relays. Upon further investigation, the base plate had been sent to me with the pins in the wrong position. I should have known it was wrong right away, but I was pressed for time and just put the wires in the Rc C Rh W1
Incorrect base plate
C * W2 W1 Rh (all upside down)
G o/b Y2 Y1 Rc (all upside down)
Once I realized what was going on. I just put Rh to G and W1 to o/b. It worked. I will go back and see if I can pop out the wire receptacles and fix the pin outs at a later date so it doesn’t confuse me at some point when i have to replace or repair.
