RTH1120 Non-programmable Electronic Thermostat Wrap the wires around a pencil to prevent them from falling into the wall. If the hole in the wall is too big, insulate it using a non-flammable material in order to avoid air draughts behind the thermostat. Installation and User Guide 1. Introduction The RTH110B non-programmable thermostat can be used to control: · a gas, fuel oil or electric furnace - 2 or 3 wires · a central air conditioner - 2 or 3 wires · a hot water system with or without pump - 2 wires · a millivolt system - 2 wires · a central heating and cooling system - 4 or 5 wires Note: This thermostat is not compatible with heat pumps or multistage systems. 2.2 Installing the New Baseplate For a new installation, choose a location approximately 5 feet (1.5 m) above the floor and on an inside wall. Avoid draughty areas (top of staircase, air outlet, etc.), dead air spots (behind doors), direct sunlight or areas near concealed pipes or chimneys. Display Adjustment buttons Remove the thermostat faceplate. Loosen the locking screw to separate the thermostat from its baseplate (the screw cannot be completely removed). Backlight button System operating mode selector Fan operating mode selector Features · System operating mode selection: heat, cool or off · Fan operating mode selection: automatic or on (continuous) · Programmable heating and cooling cycle lengths: 10, 12, 15, 20 or 30 minutes · Temperature display in °F or °C · Backlit display · Battery replacement indicator · Interchangeable faceplates (titanium, charcoal & taupe) Tilt the thermostat upwards. Mark and bore the appropriate mounting holes (using a 3/16" drill bit) or use the existing holes. Insert the plastic anchors. Pass the wires through the opening of the baseplate and fix the baseplate to the wall using the screws provided. 2.3 Connecting the Thermostat Refer to the following table for matching the wire labels with the thermostat terminals. RTH2520 terminals Rh Rc W Y G Description Heating power supply Cooling power supply Heating signal Cooling signal Fan Wire labels Rh, R, 4, V Rc, R W, W1, H Y, Y1, M G, F 2. Installation 2.1 Removing the Old Thermostat IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT POWER TO THE HEATING SYSTEM. Remove the old thermostat to access the wires. Attention: If the old thermostat was mounted onto an electrical box, it was probably powered by 120/240 volts. In this case, this thermostat cannot be used. Identify and label each wire (with the corresponding letter on the wire terminal) and remove them from the terminals. If necessary, strip the end of each wire (maximum of 1/4 inch). Note: Do not connect wires identified as C, X or B. Wrap the bare end of these wires with electrical tape. Important: The red jumper wire between Rh and Rc terminals must be removed in a 5-wire installation.

Heat relay JP2 jumper HG HE Leave the jumper in this position if you have a gas or oil heating system. Move the jumper to this position if you have an electric heating system. 2.3.2 2-wire Cooling 2.5 Installing the Batteries Cool relay 2.3.3 3-wire Heating Pull out the battery cover. Heat relay Fan relay Install the batteries as shown. Observe the polarity. Reinstall the battery cover. You will hear a clicking sound. After the batteries are installed, the thermostat performs a series of tests for approximately 5 seconds. Afterwards, the screen displays the actual temperature. It is normal that the displayed temperature will be higher than the ambient temperature if you hold the thermostat in your hands. It will display the ambient temperature after the thermostat is installed on the wall. By default, the setpoint is 70°F (21°C). 2.3.4 3-wire Cooling Cool relay Fan relay 2.6 Completing the Installation 2.3.5 4-wire Heating and Cooling Heat relay Cool relay Fan relay Once the baseplate and the batteries are installed, mount the thermostat on the baseplate. Secure the thermostat using the locking screw and install the faceplate. Apply power back to the system. 2.3.6 5-wire Heating and Cooling Fan relay Heat relay Cool relay Note: Remove the red jumper wire between terminals Rc and Rh. RTH1120 69-1875EF 22/2/06 2/4 3. Basic Functions 3.1 System Operating Mode Use the selector switch to place the system in Heating mode (HEAT) or Cooling mode (COOL), or to turn the system off. Note: When you place the thermostat in Cooling mode, you might need to wait up to five minutes before cooling can start. This is a safety feature for the compressor. will flash on the screen until cooling can start again. 4. Configuration Menu DISPLAY DESCRIPTION Temperature display Heating cycles per hour 1 Cooling cycles per hour 1 1 DEFAULT °F 4 4 SETTINGS °C or °F 2, 3, 4, 5 or 6 2 2, 3, 4, 5 or 6 3 3.2 Fan Operating Mode Use the selector switch to set the fan to automatic mode (AUTO) or continuous mode (ON). Note: This switch is not used if you have a 2-wire installation as the fan is not connected to the thermostat. The fan operates only when the heating or cooling system is On (typical setting). The fan operates continuously. Use this setting to improve air circulation and air cleaning. AUTO ON When either the heating or cooling parameter is displayed, use the system mode selector switch to alternate between the two parameters. 2 For optimal heating control, use the setting that matches your system as follows: 2=30 min (steam or gravity), 3=20 min (hot water or 90%+ high-efficiency furnace), 4=15 min (gas or oil), 5=12 min (alternate setting for gas or oil), 6=10 min (electric). 3 The corresponding cooling cycle lengths are as follows: 2=30 min, 3=20 min, 4=15 min, 5=12 min, 6=10 min. To access the configuration menu, press the backlight button for 3 seconds. To go to the next parameter (menu item), briefly press the backlight button. To modify a parameter, press . Repeat steps 2 and 3 if necessary. Press the backlight button for 3 seconds to exit the configuration menu. 3.3 Displaying the Temperature The actual temperature is normally displayed. To view the setpoint, press once on either of the buttons. The setpoint is displayed for 5 seconds along with the icon.
