Have a query regarding a morco combi boiler in a mobile home. It's set up with a link on the thermostat connections within the control panel and heat is controlled by Trv's. I'm planning on adding a hive thermostat to give me more control and intend to use the app. My question is, when the DHW is drained over the winter can I still run the CH via the app. We would use the mobile home a few times over the winter and it would be handy if we could turn the heating on via the app a few hours before hand. I would have to leave the boiler on but the hive app thermostat switched to off. Would any damaged be caused to the DHW side by running the heating. Thanks
