2. If an existing thermostat is being replaced: a. Remove existing thermostat from wall. b. Disconnect wires from existing thermostat, 1 at a time. Be careful not to allow wires to fall back into the wall. c. As each wire is disconnected, record wire color and terminal marking. - Page 7 3. Open thermostat (mounting base) to expose mounting holes. The base can be removed to simplify mounting. Press the thumb release at the top of the thermostat and snap apart carefully to separate mounting base from remainder of thermostat. 4. Route thermostat wires through large hole in mounting base. Level mounting base against wall (for aesthetic value only—thermostat need not be level for...

2 seconds. It will be one of PH or PC (if HP, AC, H or C is displayed, the thermostat is configured incorrectly to operate a PTAC). See explanation under Step 3, Option 01 below. A heat pump thermostat, configured to operate a HeatCool unit (see Option 1 below), will display PC. A HeatCool thermostat cannot be configured to operate a HeatPump unit. - Page 12 Configuration Options - - Selection: Option 01 - - Equipment type A PTAC HeatPump thermostat (PTACSTAT- -NP- -HP- -x), valid selections are PH or PC - - Default is PH. A PTAC HeatCool thermostat (PTACSTAT- -NP- -AC- -x), the only valid selection is PC - - Default is PC.
- Page 13 C — Thermostat output (O/B) will have 24VAC in cooling mode, 0VAC in heating mode. H — Thermostat output (O/B) will have 0VAC in cooling mode, 24VAC in heating mode.
- Page 14 Selections: 01 through 06 — Default is 02. Sets the minimum allowable number of degrees between heating and cooling setpoints. One setpoint will “push” the other to maintain this difference. Option 13 - - Room Air Temperature Offset Selections: - -5 to 5_ F — Default is 0. This option selects the number of degrees F to be added to the displayed temperature to calibrate or deliberately miscalibrate the measured room temperature.
- Page 15 Selections: ON, OF — Default is OF. When ON is selected and the thermostat is not battery operated, a low level continuous display backlight is always on. With OF selected, the backlight is only on for a short time after a key is pressed.

OPERATING THE THERMOSTAT NOTE: Should the thermostat lose power, it will turn back on with the last settings prior to the power outage. Button Identification A08088 Fig. 5 - - Button Identification a - - FAN Selects whether the fan operates continuously (on) or in cycle mode... - Page 19 The display has two levels of lighting, high level and continuous low level. High level lighting comes on for 10 seconds any time a button is pressed. Continuous low level lighting is only available if the thermostat is operated from 24VAC. It is not available with batteries. Continuous low level backlighting is a configurable option (see configuration settings above).
- Page 20 Setting the temperatures for heating and cooling Your thermostat is installed with the heating set at 68_F and the cooling set at 72_F. You can use these or change them so your room is as warm or as cool as you would like it to be.
- Page 21 Turn the unit off To use the thermostat to turn off the heating and cooling system, press the mode button on the left repeatedly until the display shows off in the upper left.
