here was a fault with the old actuators being plugged into a different circuit to the heat pump so had to wire down to gpo on same RCD.<br />
<br />
Wire plug base into manager box for hot water control, had to wire second plug base into box for hot water & also wire them to the 20A circuit for the hot water<br />
<br />
Disconnect old actuators & wire new ones into relay box<br />
<br />
Wasted time trying to commission system while thermostats were not setup. Heat pump manager could not identify thermostats until they had been setup by client.<br />
<br />
Extra time involved because unit was off the ground and a pain in the ass to get to<br />
<br />
Installed new board to try and get heat pump working, still wouldn't work until I asked client to setup thermostats. When thermostats were setup the manager was able to identify the controllers and finish commissioning.
