reached and key or a function has been locked out.
“Spanner” Icon. I
If you see a spanner ICON flashing on your LCD, the
installer has left your thermostat in “Commissioning mode”.
Although your thermostat will operate your heating and
cooling system whilst in “commissioning mode”, all active
safety and energy conservations delays have been disabled.
It is therefore HIGHLY recommended that you contact your
installer and request that the installer mode be disabled.

functions within the iSTAT thermostat control logic. If such a function has
been prevented based on the outside air temperature, the word “LOCKED”
