If the DOWN key is released early, the number will return to 10 and the reset will not occur. Step 4 — Check Thermostat Operation The PTAC Comfort Series non- --programmable thermostat has a built- --in installer test capability. Use it to check thermostat and equipment operation without delays or setpoint adjustments to force heating or cooling. NOTE: Any time delays or protections built into the equipment will still be active. 16 To enter the Installer Test mode, use the same process as is used to enter Installer Configuration, only hold the FAN key longer. More specifically, press and hold the FAN for about 15 seconds until the display reads In on the left and S in the smaller display. The MODE will be OFF. The MODE key (upper left) can now be used to select heat, cool, or emergency heat (HP only). Selecting one of the available modes will immediately command the equipment to turn on in that mode. The request will stay active for 3 minutes and then return the mode to off. With HeatPump thermostats (having 2 stages of heating), the request will be active for 3 minutes on each stage. Changing the mode to OFF will terminate any running test immediately. During any test, the display icons will be displayed the same as for normal operation of that stage, as follows: SELECTED MODE DISPLAY ICONS off off cool cool on heat heat on, aux heat on Em Heat (HP only) aux heat on To terminate the Installer Test mode, press the up or down temperature buttons. If the thermostat is left in Installer Test mode, it will revert back to normal operation after 15 minutes. Checklist 1. Run equipment through several heating and cooling cycles to ensure proper operation. 2. If the equipment is to be left in operation, setpoints and operating mode must be properly selected. 3. Put away tools and instruments and clean up debris. 17 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 (auto) b - --MODE Selects whether thermostat is set for heating, cooling, emergency heat (heat pump system only) or off c - --UP Increases the temperature (or adjusts the screen selection up when setting advanced programming features) d - --DOWN Decreases the temperature (or adjusts the screen selection down when setting advanced programming features) 18 Display backlighting 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). 415732891161012 A08089 Fig. 6 - --On screen indicators On- --Screen Indicators 1 2 3 Fan mode - -- on or auto Thermostat mode is off Current Setpoint or Room temperature (if configured to display room temp) 19 4 Thermostat mode is Cool 5 Thermostat mode is Heat 6 Thermostat mode is emergency heat 7 Fahrenheit 8 Celsius 9 Battery strength indicator 10 Aux Heat is On 11 Compressor is On (if flashing, it is waiting to come on) 12 Current setpoint (if configured to display room temp) 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. These steps will hold the temperature where you set it. 1. To change the heating temperature, press the mode button on the left until the screen says heat. 2. Press the up or down button located on the right side of the display until you reach the desired temperature. 3. To change the cooling temperature, press the mode button on the left until the screen says cool. 4. Press the up or down button located on the right side of the display until you reach the desired temperature. Using the fan When the fan is on, it helps distribute air for a more even temperature in all spaces. You can set the thermostat so the fan runs continuously (on) or only 20 during your heating and cooling cycles (auto mode, sometimes known as cycle mode). The thermostat is set at the factory to run automatically as needed (auto). Here’s how to change the setting so it runs continuously. 1. Press the fan button on the left. The display message will change from auto fantofan on. 2. To return the fan to auto mode, press the fan button again. You will see fanautoonthe display. Using emergency heat (heat pump units only) Emergency heat is useful when the automatic auxiliary heat system can’t keep up with demand. (Units with heat pumps use “auxiliary heat” when it’s too cold outside for the heat pump to heat the space. The display indicator for this is aux heat on.) Here’s how to set your thermostat to use emergency heat. 1. Pres...
