Boy1925 Posted January 4 Share Posted January 4 Yes indeed although whilst I anticipate that my engineer in fitting the new sensor will have been astute to the possibility that the same problem could reoccur, there are many other wires and checking them all will not be easy. The one which caused the problem on this occasion was partially hidden behind the pcb. Link to comment Share on other sites More sharing options...
HughF Posted March 18 Share Posted March 18 I’m involved in the installation of an ex display therma-v that didn’t come with the in-room display/controller and the dhw tank sensor. I’ve got part numbers and sources for those, but could someone sanity check my thoughts: It’s a 2 core cable from the display to the heat pump? The therma-v has a built in flow/buffer temperature sensor? There isn’t a volt-free call for heat input, just a 240v thermostat wiring strip? I should add that I don’t have the manual, just going off the wiring diagram on the inside of the door. @adam Huttel Link to comment Share on other sites More sharing options...
JohnMo Posted March 18 Share Posted March 18 You can get around the DHW temperature probe with an on off thermostat and two resistors. I works and is working currently for me. https://forum.buildhub.org.uk/topic/36003-pt100-cylinder-probe-wireless-connection/ Link to comment Share on other sites More sharing options...

It's nicer in some ways than the Cool Energy, but much worse in other ways... Edited March 18 by HughF 1 Link to comment Share on other sites More sharing options...
ReedRichards Posted March 21 Share Posted March 21 I think somewhere back here is a post that says that the current Therma V generation controller does not work with the previous generation heat pump. Better check how long this ex-display model was on display. Link to comment Share on other sites More sharing options...
