Changing Battery on TRV

Options

Hi,

Just a heads up when changing a trv battery...

Tado instructions say;

-------------------------------------------------------------------------------------------------------

"To restart the Smart Radiator Thermostat, remove the batteries from the device and wait 10 seconds before putting them back, then close the battery compartment. Then wait 1 minute before you remount the device. This ensures the device will calibrate successfully. Your device will then restart automatically"

---------------------------------------------------------------------------------------------------------

The problem here is that you need to dismount the trv, remove the batteries, wait 10 seconds, fit new batteries, close the compartment, then wait 1 minute...but because the trv head is still dismounted it can't calibrate, because it is not in contact with the pin on the valve body, resulting in E1 & E2 faults.

However if you ignore the "wait 1 minute" and remount the trv head immediately, then no fault codes appear and the trv works fine.

Maybe the 1 minute delay was needed previously and the Tado instructions have never been updated?? but the delay causes faults E1 & E2 on my system..

    Not for me squire! Always wait 1 minute with never a fault!
