INSTALLER CONFIGURATIONINSTALLER CONFIGURATION
INSTALLER CONFIGURATION
INSTALLER CONFIGURATIONINSTALLER CONFIGURATION
BEFORE TURNING POWER ON, please read the following instructions. Before operating the system, you must configure the thermostat to operate properly with your equipment.
The thermostat, as it comes from the factory, is configured to operate a
standard multi-stage electric forced hot air system with a single stage air conditioning compressor
and fan. In this configuration, the thermostat will turn on the fan immediately on a call for heat. If you are unsure whether your system requires the thermostat to control the fan, contact your furnace/air conditioning system manufacturer or a qualified heating/air conditioning service person.
Installation
Your new thermostat has an Installer menu, which allows you to custom­ize the thermostat to meet your requirements.
(The thermostat also has a User
menu and a Keypad Lockout menu; these menus are explained
further in the CONFIGURATION section.)
The menu settings can be changed at any time to meet system or personal requirements.

(Installer table steps 7 and 8.) These items allow a selection of 0 to 127 seconds of fan-off delay after the thermostat has satisfied the call for cool, or a fan-on delay of 1 to 30 seconds on a call for cool (or heat pump compressor activation).
The fan-off delay allows the fan to continue running after the compres­sor has shut off. This distributes the cool air that would otherwise stay trapped in the air conditioning coils through the ducts. Ideally the timing would be set so the fan shuts off just as the cool air is exhausted. If this timing is set too long the fan may begin blowing warm air before it shuts off. Shortening the fan-off delay will prevent this.
A short delay to allow the A-coil
to cool off (or warm up in heat
pump) before the fan turns on may
be preferred. This also allows the
compressor and the fan to come
on at slightly different times,
which allows full power to the
compressor on start up. Recom-
mended setting for fan-on delay is
10 seconds or less. A system that
does not have a high head pressure
cutout should have a delay of 10
seconds or less.

The fan-off delay allows the fan to continue running after the burner, heating element, etc. has shut off. This distributes the heat that would otherwise stay trapped in the ducts. Ideally the timing would be set so the fan shuts off just as the warm air is exhausted. If this timing is set too long the fan may begin blowing cool air before it shuts off. Shortening the fan-off delay will prevent this.

(Installer table step 10; heat pump only) This item controls heat pump compressor operation with a fossil fuel auxiliary. This menu item may eliminate the need for a separate fossil fuel kit, although we recom­mend that you consult the heat pump system manufacturer before
using this feature instead of a kit. This item will allow the thermostat to turn the heat pump compressor off if the auxiliary is on for more than one minute, to prevent compressor head pressure from getting too high. To use this feature instead of a kit, select PUMP OFF.

(Installer table step 11). This thermostat is capable of protecting the system against premature compressor failure by “locking out” the compressor for at least five minutes after each cycle. When the thermostat is in compressor lockout, the word COOL will flash on the display. With heat pump systems, the word HEAT will flash if the lockout occurs during a heat cycle. During this period, the compressor will not be energized.

(User menu, Item 1) The room temperature display can be adjusted to read higher or lower by following the User menu and adjusting the temperature to a higher or lower value. The thermostat is calibrated at the factory to display a very accurate room temperature, but due to various conditions and/or personal preference, you may wish to adjust the thermostat display higher or lower (up to 5°F). For example, if the thermostat displays a room temperature of 70° but you want it to display adjust, refer to the CONFIGURA­TION section (page 24, item 1).

(User menu, Item 2) EMR causes the thermostat to start operating the system early in order to make the building temperature reach your program setpoint at the time you specify. In multistage heating, the thermostat will start 8 minutes early for every 1°F difference between the room temperature and the next programmed temperature. In cooling and heat pump applications, the thermostat uses 15 minutes per °F. For heating applications in large buildings where extra time to reach the set temperature may be desired, EMR Long may be selected. When EMR ON L is selected in the user menu (page 24, item 2) the thermo-
30
stat uses 15 minutes per °F. EXAMPLE: If the temperature in
the room is 65°F and the thermostat is programmed for 70°F at 7 AM, the thermostat will start approxi­mately 40 minutes early. The difference between the room temperature (65°F) and the setpoint (70°F) is 5°. 5° X 8 minutes per °F = 40 minutes. The setpoint on the display will actually change to display 70° about 40 minutes early.
The maximum time the thermostat can start early in heating is 75 minutes (or 3 hours, 45 minutes if EMR ON L is selected). The maximum time in cooling and heat pump applications is 3 hours and 45 minutes. Cooling or heat pump
applications start earlier because it takes longer to reach the desired temperature. This feature also minimizes the use of the auxiliary stages if conditions are such that the compressor stages are adequate to reach the desired setpoint.

The thermostat uses 24 VAC power supplied by the system for normal operation. The electrolytic capacitor allows you the added convenience of programming the thermostat even when not attached to the wallplate, Attach the thermostat to the wallplate and allow the capacitor to charge for at least one hour. After the capacitor is charged you will have approximately one hour after removing the thermostat from the wallplate to configure and program the thermostat.

On installation, or when power is restored after a total power loss to the thermostat, your thermostat will automatically maintain a heating
37
temperature of 62°F (16°C) and a cooling temperature of 85°F (29°C).
If the 24 volts from the Heating/ Cooling transformer is lost, your thermostat will lose its display in 2 minutes and may lose time in about 5 hours. This hold up time will be much shorter if the control had not been powered for at least 4 hours prior to the power outage. When power is restored, the thermostat will return to the temperatures listed above.

Your thermostat is designed to determine the optimum time to activate the second stage. Simply raising the temperature in heating or lowering it in cooling will not always force the thermostat to bring the second stage on quickly. There is a time delay from 0-30 minutes depending on the performance of the first stage of the system.
Example: For the last 2 hours the thermostat is set on 70° and the room temperature is 70° with the
equipment using only the first stage of heat. Since the equipment is keeping the temperature within 1 degree of setpoint, the thermostat will delay second stage for a longer time if you manually raise the temperature or if the room tempera­ture quickly changes. Once the second stage comes on, it will come on sooner the next time there is a difference between the setpoint and the room temperature. The net effect of the staging program is that when the first stage is capable of making temperature the second stage will delay longer. When the thermostat calculates that first stage cannot make temperature in a reasonable time, the second stage will come on sooner. This built in function automatically optimizes the use of
38
additional stages of heat or cool. Should your needs require a modification of the factory default settings, refer to Heat Fast or Cool Fast instructions on page 31.
