It serves to impose the cycles per hour limits. It can be defeated for one cycle by simultaneously pressing the FAN and UP buttons. 41 Ten.Minute Staging Timer In multistage heating or cooling, this timer prevents any higher stage from turning on until preceding stage has been on for 10 minutes. When staging between compressor and electric heat or between compressor and furnace heat, the time is configurable. The timer is configurable via Option 17. This timer is overridden if temperature error

When the keypad lock selection is turned on, the padlock icon will be displayed. To unlock the keypad, press and hold the UP/DOWN buttons simultaneously for five seconds. When the keypad is unlocked, the padlock icon will turn off. The keypad will remain unlocked for two minutes after the last button press. After two minutes with no button presses, the keypad will lock again. The keypad will not lock in the software configuration mode or in the installer test mode. Default is OF (off). 31 Option

Route wires through large hole in Equipment Control Module. Level Equipment Control Module against wall (for aesthetic value only . Equipment Control Module need not be leveled for proper operation) and mark wall through 4 mounting holes. To avoid unintended bending of wall plate plastic, use all 4 screws and anchors. 2. Drill four 3/16.in. mounting holes in wall where marked. Thermostat may be mounted to a standard junction box if desired. Hole pattern on Equipment Control Module matches juncti

GENERAL Totaline® thermostats are wall-mounted, low-voltage thermostats which maintain room temperature by controlling theoperation of an HVAC (heating, ventilation and air conditioning) system using separate heating and cooling set points andauto-changeover capability. Batteries are not required. During power interruption theinternal memory stores set points indefinitely. OPERATION Thermostat Display — The thermostat display is located in the top center of the thermostat. See Fig. 1. The follow

If it reads 24 vac, replace the Apollo control. If it reads 0 to 2 vac, check the C1 contactor and the unit transformer. The Control Will Not Energize Second Stage Cooling 1. The thermostat is not displaying the second stage indicator. A decimal point on the thermostat display screen is the indication that the thermostat is asking for second stage. a. Check to see if the space demand is equal to or greater than 2° F. The control must see a 2° F demand before it will call for second stage. b. Che

2. Wire the connector board to the Apollo control with a short piece of field-supplied 5-conductor cable. 3. Plug the thermostat into the connector board. a. If thermostat powers up, there is a wiring problem. Find the open or shorted wire, or replace the wiring between the thermostat and the Apollo control. b. If the thermostat does not power up, try another thermostat. If the new thermostat powers up, replace the off thermostat. If the new thermostat will not power up, replace the Apollo contr

This will create a Heat Stage 1 demand. A small triangle to the left of this HEAT icon will flash or come on continually. Flashing means the equipment is going to turn on but is presently being held off by a system timer. (See Operational Information for timer descriptions.) Defeat timer by pressing INCREASE TEMPERATURE button (up and FAN buttons together). This will make the triangle stay on and turn on Heat Stage 1. To turn off, reduce heating set point below room temperature. The heating and

3. Press MODE button once. The SET icon will come on. The display now shows Option 01 setting. 4. Use up and down buttons to move between the available Option 01 values of 1 to 9. Factory default is 3. 5. Press MODE button again to return to Option 01. The SET icon will now be off. 6. Use up and down buttons to select another Option, or press FAN button to exit configuration mode. OPTION 02 - --CLEAN FILTER TIMER This option selects the number of hours of blower operation (heating, cooling, or f

4. If the mode is set to EHEAT, auxiliary heat turns on for three minutes, then the mode returns to OFF. Terminating Installer Test After 15 minutes of inactivity (no button presses by the installer), thermostat will automatically revert to normal operation. Pressing RESET FILTER any time during installer test will terminate installer test and return the thermostat to normal operation. Step 5 - --Check Thermostat Operation Fan Operation 1. Press FAN button, starting continuous fan operation. FAN
