Mounting the WPT
2.1.1
Remove the Existing Thermostat
1. Remove the external cover of the existing thermostat, if any.
2. Locate and remove the mounting screws and carefully remove the unit from the
wall along with the attached pneumatic tubes.
3. Detach the old thermostat unit from the air tubes carefully. The air tubes may not
have a lot of slack – be careful that the tubes do not retract into the wall. In a 2-
pipe system, note the positions of branch and main tubes.
