Operation Instructions

Initial Setup

1. Insert Batteries: Install 2 AA alkaline batteries in the rear compartment along the top, removing the battery tag to activate. Replace when “LO BATTERY” appears (approximately every 2 years). If the home is unoccupied for over 3 months and the battery indicator shows low, replace batteries before leaving.
2. Power On: If hardwired, ensure 20-30 VAC is supplied via the C terminal. The touchscreen should display the home screen with temperature and system status.
3. Configure System:

Press MENU, then hold INSTALLER CONFIG for 5 seconds to access the configuration menu.
Select system type (SS1, MS2, HP1, HP2), fan settings (Auto, On, Programmable), and options like keypad lockout, setpoint limits, or filter change timer.
For heat pumps, set O/B to O (cool) or B (heat) based on system requirements.
Exit by pressing RUN SCHED or waiting for the display to return to normal.

Operating the Thermostat

1. Select Mode: Press SYSTEM to choose HEAT, COOL, AUTO, EM (emergency heat for heat pumps), or OFF.
2. Adjust Temperature: Press up/down arrows to set the desired temperature. In AUTO mode, set separate heat and cool setpoints (minimum 4°F difference).
3. Fan Control: Press FAN to select AUTO (runs with heating/cooling) or ON (continuous). For commercial applications, configure occupied damper control in INSTALLER CONFIG.
4. Verify Operation:

In HEAT mode, set temperature 1°F above room temperature; “System On” should display, indicating heating stage energized.
In COOL mode, set temperature 1°F below room temperature; “System On” should display after up to a 5-minute compressor delay.
In EM mode, set temperature 3°F above room temperature; “System On +2” indicates additional stages (e.g., auxiliary heat).

Temperature Display Adjustment

1. Press MENU to access USER MENU.
2. Navigate to Temperature Adjustment option.
3. Use up/down arrows to adjust the displayed temperature by ±5°F to match the actual room temperature.
4. Press RUN SCHED to save and exit.
Note: Use a separate thermometer for calibration. Relocate the thermostat if near drafts, heat sources, or exterior walls.

Troubleshooting

No Display: Check battery polarity or replace with fresh AA alkaline batteries. Verify C wire connection for hardwired setups. Reset by removing R and C wires and batteries for 2 minutes (do not short R and C together). If “Call For Service” displays, check for system faults.
No Heat/Cool: Ensure SYSTEM is set to HEAT/COOL/EM, setpoint is above/below room temperature, and circuit breaker is on. Check for compressor delay (up to 5 minutes, indicated by flashing setpoint). Verify wiring, especially O/B for heat pumps. If no response, contact a professional technician at 1-800-284-2925.
System Runs Continuously: Set SYSTEM to HEAT or COOL (not AUTO) and FAN to AUTO. If the air conditioner runs without cooling demand, set Power Stealing Switches to “Off” to disable Power Stealing Assist. Verify setpoint settings.
Inaccurate Temperature: Calibrate in USER MENU (±5°F). Ensure thermostat is not near drafts, heat sources, or exterior walls. If using remote sensors, check sensor connections.
Erratic Operation or “Call For Service”: Reset by removing batteries and R/C wires for 2 minutes. If “Keypad Lockout” displays, unlock by pressing MENU and RUN SCHED simultaneously and entering the code. If issues persist, contact a technician.
Thermostat Changes Setpoint Randomly: Perform a factory reset (MENU, hold INSTALLER CONFIG, select reset). If issue persists, verify wiring and system compatibility; the thermostat may be faulty.[](https://www.amazon.co.uk/Emerson-1F95-0680-Commercial-Programmable-Thermostats/dp/B003EU9TWI)

Installation Instructions

Warning: Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code. To prevent electrical shock or equipment damage, disconnect power at the main fuse or circuit breaker before installation.

Remove Old Thermostat

Before removing wires, mark wires for terminal identification to ensure proper connections to the new thermostat. Take a picture of the wiring for reference.

Installing New Thermostat

Pull the thermostat body off the thermostat base. Do not force or pry to avoid damage.
Place base over the hole in the wall and mark mounting hole locations using the base as a template.
Move base out of the way, drill mounting holes. Use plastic screw anchors if existing holes are too large.
Fasten base snugly to the wall using mounting holes and two mounting screws. Leveling is for appearance only and does not affect operation.
Connect wires to the terminal block on the base using the appropriate wiring schematic (refer to equipment manufacturer’s instructions).
Push excess wire into the wall and plug the hole with fire-resistant material (e.g., fiberglass insulation) to prevent drafts.
Carefully line the thermostat up with the base and snap into place.

Battery Location

Includes 2 AA alkaline batteries at the factory with a battery tag to prevent power drainage. Remove the tag to engage batteries.
To replace, set system to OFF, remove thermostat from the wall, and install batteries in the rear along the top. Use premium brand AA alkaline batteries like Duracell or Energizer.
If the home will be unoccupied for over 3 months and the battery level indicator shows low, replace batteries before leaving.

Power Stealing Switches

Leave switches in the “On” position for most systems. Details in the following table:

Thermostat Power Method	Switch Position/Description
Battery Powered, no 24 Volt system	Switches “On”, thermostat runs on batteries.
Hardwired with Battery Back-up, for 24 Volt systems with common connection from transformer to “C” terminal	Switches “On”, thermostat runs on power directly from transformer with battery back-up.
Battery Powered with Power Stealing Assist, for 24 Volt systems with no common connection	Switches “On”, thermostat runs on batteries and supplemental power drawn through heat or cool circuit.

Caution: Power Stealing Assist may cause issues on systems with high impedance electronic modules (e.g., furnace draft inducer motor running with no call for heat, furnace fan not turning off). If incompatible, set switches to “Off” to operate on batteries, correcting the condition.
