i have recently had a hive controller installed in my y type ch system, bosch greenstar 18 boiler , before the hive was firtted everything was working as expected.
now my potterton water tank thermostat ptt2 doesnt seem to be registering high temp, the water and CH are working proberly through the hive, the MV is working proberly moving to all positions, the boiler is firing on and going off with the hive timer and room thermostat but the pump never goes off....could it be the faultly hw thermostat is causing this or has the pump bee wired to constant live somehow??
