I've just moved into a new build property with a dual zone heating system. The downstairs thermostat is meant to control the downstairs radiators and the radiators to upstairs bathroom and ensuite. The upstairs thermostat is just meant to control the bedroom radiators.
When the downstairs control is on (and upstairs off), the raditator in main bedroom heats up (no other bedroom radiators heat up), but not the radiator in the ensuite.
When the upstairs control is on (and downstairs off) the radiator in the main bedroom does not het up on, but the radiator in the ensuite does.
Does this mean that there is a problem with the pipe connections, or could there be some other reason ?
