White Rodgers F145-1378 Configuration, Remote Sensor Calculated Priority Average, Comfort-SetII

CONFIGURATION

Comfort-Set II

Single Stage Models: Verify jumper wire W-22on the back of the thermostat (not the subbase) has been clipped. Multi-stage and Heat Pump Models: Verify jumper wire W- 18 on the back of the thermostat (not the subbase) has been clipped.

Comfort-Set III/Comfort-Set 90/90 Series

Single Stage Models: Verify jumper wire W-922on the back of the thermostat (not the subbase) has been clipped. You must also enable the remote sensor option in the Installation Instructions, Configuration Menu.

Multi-stage and Heat Pump Models: When installing a remote sensor you must enable the remote sensor option in the Installation Instructions, Installer Menu.

REMOTE SENSOR CALCULATED PRIORITY AVERAGE

1F93-380, 1F94-371, 1F95-371, 1F95-377, 1F95-391

Single stage thermostats accept only 1 remote sensor. 90 Series multi-stage and heat pump thermostats accept up to 3 indoor remote sensors and can be assigned sensor priorities.

Tables 1-3 show how priority (LO, AVG, HI) effects the room temperature calculation. The example below table three shows the calculation of each remote sensor and how it uses them to arrive at room temperature average.

Table 1: Remote Sensor A configured as a LO priority sensor

Remote	Sensor	Priority
Sensor	Priority	Multiplier	Room Temperature	Averaging		Calculation
SA	LO	1	70°F (Sensor Temp.)	1 x 70	= 70 (Priority Multiplier x Room Temp.)
Table 2: Remote Sensor B configured as a AVG priority sensor
Remote	Sensor	Priority
Sensor	Priority	Multiplier	Room Temperature	Averaging		Calculation
SB	AVERAGE	2	75°F (Sensor Temp.)	2 x 75	= 150 (Priority Multiplier x Room Temp.)
Table 3: Remote Sensor C configured as a HI priority sensor
Remote	Sensor	Priority
Sensor	Priority	Multiplier	Room Temperature	Averaging		Calculation
SC	HI	4	80°F (Sensor Temp.)	4 x 80	= 320 (Priority Multiplier x Room Temp.)

The example below lists three sensors each with a different priority and room temperature. All three sensors are combined in the calculation to display the average temperature. The priority multiplier shown in the tables above causes a sensor with low priority to carry less weight in the calculated average. A sensor with a HI priority setting contributes more to the calcu- lated average. Assume that the building in which the thermostat is located has three indoor remote sensors (SA, SB, SC) that have different room temperatures (70, 75, 80). The calculated average will be displayed as the room temperature shown in the example below.

Example: Remote Sensors A, B, and C configured as a LO, AVG, and HI priority sensors

Remote	Sensor	Priority
Sensor	Priority	Multiplier	Room Temperature	Averaging Calculation
SA	LO	1	70°F (Sensor Temp.)	1 x 70	= 70 (Priority Multiplier x Room Temp.)
SB	AVERAGE	2	75°F (Sensor Temp.)	2 x 75	= 150 (Priority Multiplier x Room Temp.)
SC	HI	4	80°F (Sensor Temp.)	4 x 80	= 320 (Priority Multiplier x Room Temp.)
				Avg. Calc. (540)/Sum Priority Mult. (7)
				540/7 = 77°F (Calculated Displayed Temp.)
