CAUTIONS

• The factory installed clock backup battery is not replaceable and rechargeable. There may be a risk of explosion if a wrong type of clock backup battery battery is used. Use only the factory installed non-replaceable battery (Compatible battery type CR 1220, Nominal battery voltage 3 V) and do NOT recharge the battery.
• Even used batteries may cause severe injury or death.
• Do not force discharge, recharge, disassemble, heat above 212°F (100°C) or incinerate. Doing so may result in injury due to venting, leakage or explosion resulting in chemical burns.
• Call a local poison control centre for treatment information.
• Remove and immediately recycle or dispose of used batteries according to local regulations and keep away from children. Do NOT dispose of batteries in household trash or incinerate.
•  Battery must be removed from the thermostat before it is scrapped.
• Thermostat must be disconnected from the supply mains when removing the battery.
• Battery is to be disposed of safely.

Installation process

1. Power off your HVAC system
   Disconnecting the power protects you and avoids damage. After disconnecting, adjust the set temperature to confirm the system is off.

2. Carefully remove the cover from your old thermostat

3. Verify system compatibility
   Inspect the wire connections to verify system compatibility.
   CAUTION: The T961 is compatible with low-voltage (24V), single transformer systems only. If you inspect and find any of the following, then the T961 is not compatible with your system. 1) Labels on the wiring or old thermostat warning of High Voltage, 120V, or 240V connections. 2) Thick electrical wires that are connected using wire nuts. 3) If your old thermostat supports RC and RH terminals that are wired separately (not
   connected via jumper wire) If you have any enquiries about system compatibility, email support@vtechhotelphones.com.

4. Remove jumper wires (if any)
   Jumper wires are short wires between two connectors. You won’t need them.

5. Take a photo of the wires while connected to your old thermostat
   Take a photo of wire color/terminals that you can refer to later. You may also consider labelling the wires to match the terminals (R, C, G, Y, W, etc…).

6. Disconnect wires from old thermostat
   Carefully disconnect the wiring from the old thermostat. Once removed, wrap the wire bundle around a pencil to prevent them from falling back into wall.
   Mounting Option 1: Direct Wall Mounting

7. Mark the screw positions for the wall plate
   **** Hold the wall plate up to the wall where you want the thermostat to be mounted. Make sure that the wire bundle aligns near the centre of the wall plate. Verify the plate is level with a bubble level then mark the screw positions through the screw holes in the wall plate.

8. Attach the wall plate
   Using your marks as reference, drill 2 holes and install the provided wall anchors. Route the wires through the opening in the center of the wall plate, then secure it to the wall with the provided screws. The slots in the wall plate will help to compensate for any minor misalignment.

Mounting Option 2: Direct Wall Mounting with Deco Plate Kit

1. Mark the screw positions for the deco plate
   Hold the deco plate up to the wall where you want the thermostat to be mounted. Make sure that the wire bundle aligns near the centre of the deco plate. Verify the plate is level with a bubble level then mark the screw positions through the screw holes in the deco plate.

2. Attach the deco plate and wall plate

3. Push the cover towards the deco plate until it clicks into place.

4. Using your marks as reference, drill 2 holes and install the provided wall anchors. Route  the ires through the opening in the center of the deco plate, then the wall plate.

5. Align the screw holes and secure them to the wall with the provided screws. The slots in the wall plate will help to compensate for any minor misalignment.
   

Mounting Option 3: Junction Box Mounting with Deco Plate Kit

1. Attach the deco plate and the wall plate

2. Attach the deco plate to the junction box with the provided junction box screws.

3. Push the cover towards the deco plate until it clicks into place.

4. Attach the wall plate to the deco plate with the provided T locks.

5. Route the wires in the junction box through the openings in the centres of the deco plate and the wall plate.

6. Connect wires to the wall plate
   To wire the wall plate, refer to the wiring guide displayed in the system profile that you created for your HVAC system using the EC Tool Pro App or the T961NN50 Wiring Guide.
   Once all wires are securely connected, press the wires down to ensure they are flush with the wall plate.

7. Attach the thermostat
   Swing the thermostat into position by engaging the lugs at the top of the wall plate before pushing it carefully home into its plug-in terminal block.
   Lock the thermostat into place by tightening the 2 Phillips screws located on the bottom edge of the thermostat.
   

8. Switch the power back on
   Turn on power to your HVAC system. When the thermostat powers up, verify functionality.
