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 icon turns on. 2. Press FAN button again, stopping fan operation. FAN icon turns off. (Some fan coils have 90 second fan off delay, so fan may not stop immediately.) Checklist 1. Run equipment through several heating and cooling cycles to ensure proper operation. 2. If equipment is to be left in operation, setpoint and operating mode must be properly selected. 3. Put away tools and instruments, and clean up debris. 4. Review Homeowner’s Guide with owner. 5. Leave literature packet with owner.

Fig. 3 - -- HP Thermostat with Fan Coil Fig. 4 - -- AC Thermostat with Fan Coil WIRING DIAGRAM NOTES: 1. Furnace must control its own second- --stage heat operation via furnace control algorithm. Refer to indoor equipment Installation Intructions for proper setup. 2. See Option 5 information to convert HP thermostats to AC thermostat operation. 3. As an option, lock the furnace into low- --heat operation and let O/B control high- --heat operation. Refer to indoor equipment Installation Instructions for proper setup. 4. O/B can control second- --stage heat. Refer to indoor equipment Installation Instructions for proper setup. 5. Refer to outdoor equipment Installation Instructions for latent kit requirements (if any). 6. Terminals marked with * may not be present on equipment. 7. O/B energizes reversing valve in cooling or heating. See Option 10. 8. Refer to outdoor equipment Installation Instructions for proper setup. 9. If system is wired per diagram, the ACRDJ (jumper) on furnace control board should be removed to allow thermostat to control outdoor unit staging. 10. Refer to fan coil Installation Instructions for proper wiring. 11. If batteries are installed, C (common wire) is not required between indoor unit and thermostat. 6 OPERATIONAL INFORMATION Five- --minute Compressor Timeguard The cycle timer limits the number of times the heating or cooling equipment can be energized in one hour. If option 1 is set to a value of 1 or 2, the equipment will be allowed to energize up to six times per hour. If option 1 s set to 3 or greater, then the equipment will be allowed to energize up to four times per hour. This timer is defeated for 1 cycle when the desired temperature is manually changed. It can also be defeated for 1 cycle by simultaneously pressing the FAN button and the INCREASE TEMPERATURE button. Cycle Timer This timer prevents the start of a heating or cooling cycle until at least 15 minutes after the last start of the same cycle. Its function is to assure that equipment is not cycled more than 4 times per hr. This timer is defeated for 1 cycle when the desired temperature is manually changed. It can also be defeated for 1 cycle by simultaneously pressing the FAN mode button and the INCREASE TEMPERATURE button. Staging Timer In multistage heating or cooling, this timer prevents any higher stage from turning on until the preceding stage has been on for 15 minutes. This timer is defeated if the temperature error is greater than 5_F/3_C (usually due to a large change in desired temperature). Three- --minute Minimum On Time In normal operation, when a stage turns on, it will not turn off for a minimum of 3 minutes. Heat/Cool Setpoints (Desired Temperatures) A minimum difference of 2_ is enforced between heating and cooling setpoints. This is done by allowing one setting to “push” the other, to maintain this difference. Auto Changeover When the auto changeover mode is selected, a change from heat to cool (or vice versa) will not occur until an o...
