My diy skills don’t stretch that far. I’ll have to call in help lol. Is it a plumber or a boiler technician that I need.

As I’m sitting here it’s just after kicking in again, the 3 zone electronic timer is saying everything is off but the downstairs rads are all on.

If I flip the switch at the fuse box should that sort things out and then things off for the nite.

ALSO **** when I did that last time and turned the power back on the boiler got hot but wasn’t heating the radiators until I turned on the timer. Does that make any difference to what yere thinking

Sorry, just noticed the last sentence. If the boiler was getting hot but no hot water going to radiators then it could be that the boiler was getting demand for hot water, not heating (I'm assuming you've a hot water only setting).

Am I right I’m saying that the timer box doesn’t turn on the boiler but opens the valve that in turn starts the boiler as a sort of in demand system

Yes, typically timer/controller triggers a demand, the demand routes to a thermostat and if the temperature hasn't been reached, the demand then routes to the valve actuator. The demand to the valve actuator opens the valve and as it opens the valve it passes the demand through to the boiler.

With a smart heating system like Hive the demand sis trigger by the thermostat communicating with the Hive controllers which then sends demand directly to the valve actuator.

The time clock send a live to the room stat.if there is a demand for heat it will then send a live to the motor in the motorised valve.When this motors opens the valve, it sends a live to the boiler and the boiler will start
A double pole 5 amp spur switch turn off all power to the boiler.incl the permanent live that is in the motorised valve

Yip I’ve a separate zone for hot water. That situation only happened once, when I turned all zones off the radiators all got warm but when I turned them off the downstairs one stayed warned and I could hear the boiler kicking in and out

Lads thanks for all yere help so far. I’ve the boiler turned off at the fuse box and I’m in work for the day. I’ll see how things are tonight and call for a plumber when I’m off on Wednesday.
