the technician must install this product. Carefully read these instructions. You could damage this product or cause a hazardous condition if you fail to follow these instructions.

Installation Tips

Wall Locations

The thermostat should be installed approximately 4 to 5 feet above the floor. Select an area with average temperature and good air circulation.

Battery Installation
Battery installation is recommended even if the thermostat is hardwired (C terminal connected). When the thermostat is hardwired and batteries are installed, the thermostat will activate a compressor delay of 5 minutes when the thermostat detects a power outage from the hardwired power supply.

 Pro1 -Technologies- T855iSH- Non-Programmable- Thermostat- 9 Pro1 -Technologies- T905- Non-Programmable- Thermostat-7

Important
The low battery icon is displayed when the AA battery power is low. Whenever the thermostat detects low battery voltage from the AA batteries, the low battery icon will begin flashing on the screen for 21 days (if the batteries are not changed). If the batteries are not changed 22 days after the thermostat detects low battery voltage, the thermostat screen will only show the flashing battery icon until the buttons are pressed. If the batteries are not changed 43 days after the thermostat detects low battery voltage, the thermostat screen will only show the flashing battery icon until buttons are pressed and the set points will offset to 85°F/29°C in cooling and 55°F/13°C in heating. At this stage, set point changes can be made temporarily but, the set points will change back to defaulted values after a 4-hour period. The thermostat will continue to perform this low battery flashing, temperature offset condition until the internal voltage threshold is reached. When the thermostat internal voltage threshold is reached, all relays will be opened and the thermostat will become inoperable until new batteries are installed.

Wiring

Caution: Electrical Hazard Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

  1. If you are replacing a thermostat, make note of the terminal connections on the thermostat that is being replaced. In some cases, the wiring connections will not be color coded. For example, the green wire may not be connected to the G terminal.
  2. Loosen the terminal block screws. Insert wires then retighten terminal block screws.
  3. Place non-flammable insulation into the wall opening to prevent drafts. All components of the control system and the thermostat installation must conform to Class II circuits per the NEC Code. Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the sub base correctly or cause system operation issues.

Wiring Tips

  • C Terminal This thermostat requires a 24V common wire to the C terminal.
  • Wire Specifications Use shielded or non-shielded 18-22 gauge thermostat wire.

1 Below the humidity setpoint and heat or fan is energized.
2 Below the humidity setpoint and heat is energized.
3 Below the humidity setpoint. It will also energize the fan during a call for humidity.
4 Below the humidity setpoint.

DHM Terminal

Filter Change & Other Reminders

If the filter change reminder is enabled, you will see a reminder in the display when your air filter needs changed. The reminder will be shown in the display after your system has run long enough to require an air filter change

Resetting The Filter Change Reminder

When the reminder is displayed, you should change your air filter and reset the reminder by holding down the 3rd button from the left side of the thermostat for 3 secondsPro1 -Technologies- T855iSH- Non-Programmable- Thermostat- 19

Temporary & Permanent Hold Feature

  • Temporary Hold: The thermostat will display HOLD and RUN SCHED on the bottom of the screen when you press the or key. If you do nothing, the temperature will remain at this setpoint temporarily for 4 hours. The program setpoint will then replace the temporary setpoint.
  • Permanent Hold: With a temporary hold set, If you press the HOLD key at the bottom of your screen, you will see HOLD appear below the setpoint temperature in the display. The thermostat will now permanently stay at this setpoint and can be adjusted using the or keys.
  • To Return To the Program: Press the RUN SCHED key at the bottom of the screen to exit temporary and permanent holds.

Remote Sensor Operation

  • Option #1 – Indoor / Local Temperature Sensor “ON”:
    • The displayed room temperature will display the average temperature of the thermostat and all remote sensors.
