■■ Place Base, Figure 3, over Sub-Base and attach by tightening three captive
screws.
■■ Fasten loosely to wall using two mounting screws. Place a level against the
bottom of the Base, adjust until it is level and then tighten mounting screws to
secure.
■■ Find anticipator setting on old thermostat. Setting on new thermostat should be
the same. Do this by carefully sliding the long pointer , Figure 2, over desired
number printed on the anticipator. If old anticipator setting cannot be
determined, look on gas control on furnace, or set at at .6. During heating
season, furnace should operate about five times an hour. If adjustments are
necessary, move heat anticipator pointer slightly and recheck. NOTE: Set
pointer to 1.2 for millivolt systems.
■■ Attach front cover, Figure 1, to base.
■■ Turn electricity and gas back on and set pointer on top of thermostat to desired
temperature.
■■ FOR HEATING: Set slide switch to “Heat”. Set fan switch to “Auto”.
■■ FOR COOLING: Set slide switch to “Cool”. Set fan switch to “Auto”.
■■ FAN: For continuous blower operation, set switch to “ON”. For automatic
blower operation set fan switch to “Auto”. Thermostat will then cycle the blower
“on” and “off”.
A thermostat can only control temperature near it. If you find that it is
uncomfortable some distance away from the thermostat, change the
setting in order to compensate for this.
