Pro1 Technologies T855SH Non-Programmable Thermostat

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.

Do not install thermostat in these locations:

• Close to hot or cold air ducts
• That are in direct sunlight
• With an outside wall behind the thermostat
• In areas that do not require conditioning
• Where there are dead spots or drafts (in corners or behind doors)
• Where there might be concealed chimneys or pipes

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 it detects a power outage from the hardwired power supply

Important:
High quality alkaline batteries are recommended. Rechargeable batteries or low quality batteries do not guarantee a 1-year life span.

Getting to know your thermostat

• Displays the current room temperature
• Time and day of the week / Sensor / Humidity
• Low Battery Indicator: Replace batteries when this indicator is shown.
• Energy Efficient Globe: Indicates you are making energy efficient choices.
• Keypad Lockout: Lock the thermostat
• Program Menu Options: Show different options during programming.
• Program Time Periods – Residential: Uses 4 time periods – WAKE, RETURN, LEAVE & SLEEP. Commercial: Uses 2 or 4 time periods that appear in the text field – Occupied & Unoccupied.
• Staging Indicators: +1 will appear in the display when second stage of heat or cool is on. +2 will appear for the third stage of heat.
• System Operation Indicators: If these or the Fan indicator are flashing, it means that the system is in a delay of some type (compressor delay, cooling fan delay, staging delay).
• Hold: is displayed when the thermostat program is permanently overridden.
• Filter Change & Other RemindersSetpoint: Displays the user selectable setpoint temperature.

Wiring

• 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.
  Loosen the terminal block screws.
• Insert wires then retighten the terminal block screws.
• Place non-flammable insulation into the wall opening to prevent drafts.

Wiring Tips

• C Terminal
  • The C (common wire) terminal does not have to be connected when the thermostat is powered by batteries.
• Wire Specifications
  • Use shielded or non-shielded 18-22 gauge thermostat wire.
• Note:
  • In many heat pump systems with no emergency heat relay, a jumper can be installed between E and W2 to turn thermostat into a single stage control for Emergency Heat Operation.

This thermostat is shipped from the factory to operate a conventional heating and cooling system. This thermostat may also be configured for a heat pump system. See the “heat pump” configuration step on page 17 of this manual to configure the thermostat for heat pump applications.

Getting to know your thermostat

• LCD Display
• Glow in the dark light button Setpoint buttons
• Program buttons
• Menu button
• Fan button
• System button
• Button/battery access door Battery cover

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 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.

About The Badge
All of our thermostats use the same universal magnetic badge. Visit the company website to learn more about our free private label program.

Technician Setup Menu

• This thermostat has a technician setup menu for easy installer configuration. To set up the thermostat for your particular application:
• Press the MENU button.
• Press and hold the TECH SET button for 3 seconds. This 3 second delay is designed so that homeowners do not accidentally access the installer settings.
• Configure the installer options as desired using the table below. Use the or keys to change settings and the NEXT or PREV key to move from one step to another.
• Note: Only press the DONE key when you want to exit the Technician Setup options.
• Press the DONE key to exit.
  

Swing Setting Tip
The second stage will turn on at 2x the swing setting. The second stage will turn off when 1x the swing is reached. For example, if the swing setting is .5 degrees for heating and the thermostat is set at 70˚F, the first stage will turn on at approximately 69.5˚F. The second stage will turn on at 69˚F. The second stage will turn off at 69.5˚F and the first will turn off at 70.5˚F. If the third stage is used, it will turn on at 68.5˚F and turn off at approximately 69˚F.
