Room Thermostat 
 

Most room thermostats are equipped with user adjustable, or selectable, levels of heat 
anticipation. This feature helps to reduce the amount of room air temperature overshoot 
that occurs after a heating cycle.  
 
To adjust the heat anticipator, measure the electrical current output of the oil burner 
primary safety control to the room thermostat. (If measurement is not possible, the value 
of current output may be marked on the cover of the control). Set the thermostat heat 
anticipator to match the electrical current output of the oil primary safety control. 
 

 
! WARNING: If the burner does not operate properly after depressing the oil 
primary reset button three (3) times, turn off the electrical power to the furnace 
and close the manual oil shutoff valve. Immediately contact a qualified heating 
contractor for service. 
 
Before leaving a new installation, the installer should show the customer or end user 
where the furnace instruction manual is kept. He should also discuss the following 
points: 
 

1)  Describe the general operation of the furnace and, if properly equipped, the 

cooling system. 

 

2)  Show the location of the furnace air filter(s) and those in the duct system, if 

equipped. Demonstrate how to remove, clean, and replace the air filter(s). 

 

3)  Demonstrate how to set and adjust the room air temperature using the room 

thermostat. 

 

4)  Demonstrate how to operate (turn on and off), the heating system and, if properly 

equipped, the cooling system and the circulating air blower. 

 

5)  Show the location of the oil primary safety control in the furnace. Describe when 

and demonstrate how to depress the oil primary reset button.
