Blank Screen - the screen of the Wiser Room Thermostat is designed to time out several seconds after use, in order to save battery life.
Clock Symbol - If you have just installed your Wiser HubR or have received a new firmware update you may find that 30 minutes to an hour after installation and first connection to your WiFi network, the room thermostat screen goes blank or displays a clock symbol for up to 30 mins - this is the point at which your HubR will download the latest firmware and therefore the thermostat will go blank / display a clock symbol in order to accept updated graphics. There is no cause for concern, but please follow the steps below if this happens:
- Do not remove batteries
- Do not attempt to reset the thermostat
- Do not remove the device from the Wiser Heat app
- Wait 60 minutes, and when attempting to wake the thermostat up the screen will come back
- If you still experience issues after a few hours please contact customer services for further advice
