TB-- PAC / TB-- PHP

pressing UP and FAN buttons simultaneously or changing the setpoint will override the timer for 1 cycle.

Minimum on Timer

Once the equipment has turned on, it will remain on for a minimum of 3 minutes regardless of demand. However, the equipment can turn off in less than 3 minutes if a change in setpoint, or a change in mode occurs.

Staging Timer

If the thermostat is a heat pump model, it has 2-stage heat capability. In normal operation there is a 15-minute delay between the first and second stages of heat. The Y output will energize first, then 15 minutes later, W is allowed to come on if the thermostat determines it is not satisfying the demand.

However, if the heating demand is greater than 5_F/3_C, there will be only a 30 second delay before bringing on W.

Auxiliary Heat Indicator

When operating a heat pump and either auxiliary heat or emergency heat is active, an LCD display icon indicates this condition.

Error Messages

If the room temperature sensor fails, two dashes (--) will appear in the temperature display and all heating and cooling outputs will be turned off. The thermostat must be replaced.

If the internal non-volatile memory fails, E4 will alternately flash with the temperature on the display and all heating and cooling outputs will be turned off. The thermostat must be replaced.

Step 5 — Check Thermostat Operation

Fan Operation

1.Press FAN button. This will start continuous fan operation. FAN ON icon will turn on.

2.Press FAN button again. This will stop continuous fan oper- ation. FAN ON icon will turn off.

Heating Operation

1.Press H/C button until HEAT is displayed.

2.Press UP button until LCD readout reads 3_F/2_C above room temperature. Press UP and FAN buttons simultan- eously to defeat timers. Heating system should begin to op- erate immediately.

3.For HP thermostats only, press H/C button until EMHT (emergency heat) appears. Press UP and FAN buttons sim- ultaneously to defeat timers. Emergency heating (W is ON, Y is OFF) should begin immediately.

Cooling Operation

1.Press H/C button until COOL is displayed.

2.Press DOWN button until LCD readout reads 3_F/2_C be- low room temperature. Press UP and FAN buttons simultan- eously to defeat timers. Cooling system should begin to op- erate immediately.
