Does a warning appear on the thermostat when battery levels are becoming low and-or wifi down? What battery type does the thermostat run of?
The low battery alert will be displayed on the HR92 and on the evohome controller for that specific zone.
The most suitable batteries for the evohome controller are the rechargeable AA 1.2V NiMH 2000-2400mAh types.
The HR92 Radiator controller needs 2 AA, LR6 or AM3 Alkaline batteries.
