I have a problem with my Danfoss CP15 central heating control. The system starts up ok at the right times but eventually the two red lights start flashing together and clicking and then the system will only work with one of CH or HW switched off. Anybody else experienced this problem?
The boiler is an Ideal Classic about 12 years old. The diverter valve also 12 years old but the actuator is 6 months old.
The odd thing is this only seems to happen in the evening when the timer is on the third cycle. Mornings (1st cycle) is fine, second cycle is is on/off at 12noon, third cycle is 5:30pm to 10pm.
