Hello, blown my programmer due to it getting a drip of water on it. so looking to replace with a new one, but not sure on the wiring
Looking to get the st9400c as this looks like a simple swap? But open to suggestions and also how much harder would it be to install one with a wireless thermostat?
Photo of the current wires.
system is a gas boiler with separate hot water tank
