6. Fault Finding
Under certain circumstances the thermostat may need to be reset. This may be as a result of external
issues with equipment that the thermostat is connected to.
6.1 Factory Reset
If the screen remains illuminated but is displaying odd or unexpected data this can be resolved by
performing a factory reset. Enter expert mode and select ‘Factory Settings’ as described earlier.
6.2 Hard Reset
If the thermostat screen is blank and will not illuminate then a hard reset may resolve the issue. Firstly,
isolate the thermostat by isolating the heating unit which is powering it. Reconnect the power and check
if the thermostat is still blank, if it is proceed as below. Isolate the power again and then remove the front
from the Modulo thermostat, replace the front and then reconnect the power.
Under no circumstances remove the front cover while the thermostat is powered - this may cause
irrecoverable damage.
