If you have an electric system and the blower does not operate after instal- lation, find the factory installed yellow wire currently attached to the “Y” terminal

and move it to the “A” terminal on the sub-base.

■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.
