• Page 1: Page 1
• Page 2: Thank you for purchasing a Robertshaw thermostat. This manual will describe how to install and test the Robertshaw RS9220 thermostat. Important safety information includes turning off power at the main power source before installing, removing, cleaning, or servicing the thermostat. Read all of the information in this manual before installing or programming this thermostat. This is a 24V AC low voltage thermostat. Do not install on voltages higher than 30V AC. All wiring must conform to local and national building and electrical codes and ordinances. Do not short (jumper) across terminals on the gas valve or at the system control to test installation. This will damage the thermostat and void the warranty.
• Page 3: Install the thermostat 4 to 5 feet above the floor in an area with good air circulation and average temperature. For new installations, mount the thermostat on an inside wall, 4-5 feet above the floor. Do not install the thermostat behind a door. Do not install the thermostat in a corner. Do not install the thermostat near air vents. Do not install the thermostat in direct sunlight. Do not install the thermostat with an outside wall behind it. Do not install the thermostat near any heat or steam generating fixtures. Do not install the thermostat near any concealed pipes or chimneys. Installation at these locations will affect thermostat operation.

• Page 5: Wallplate installation This product is mercury-free. However, if this product is replacing a control which contains mercury, it needs to be disposed of properly. Contact your local waste management authority for instructions regarding recycling and proper disposal of the control. Disconnect power before installing this product. Failure to do so can cause electric shock or equipment damage. For a vertical mount, put screws on the top and bottom. For a horizontal mount, put screws on the left and the right.
• Page 6: Turn off power to heating/cooling system. Remove old thermostat but leave wallplate with wires attached. Do not remove wallplate.
• Page 7: Label the wires using the supplied wire labels as you disconnect them. Remove wallplate from the new thermostat and mount onto wall. Apply these wiring labels to each wire with the appropriate terminal designation as you remove it from the existing thermostat.
• Page 8: Mount the new wallplate using the included screws and anchors. Drill 3/16-in. holes for drywall. Drill 3/16-in. holes for plaster.
• Page 9: Connect wires by matching wire labels. If labels do not match letters on the thermostat, refer to Alternate Wiring (Conventional Systems) on page 9. Remove the metal jumper if both RH and Rc wires are present. Insert wires and tighten screws.
• Page 10: Wiring Alternate wiring (conventional systems) If labels do not match letters on the thermostat, check the chart below and connect to terminal as shown. If wires will be connected to both RC and RH/R terminals, remove metal jumper. If there is a C or X wire available then you can connect with C terminal. If there is no C or X wire then no need to connect with C terminal. If you have a heat pump without auxiliary/backup heat connect either the O or B, not both. If you do not have a heat pump, do not connect O or B. Wrap bare end of wire with electrical tape. Place a jumper (piece of wire) between Y and W if you are using a heat pump without auxiliary/backup heat.
• Page 11: Wiring Terminal designations include various components such as 24 VAC common, heat pump reversing valve, heat relay stages, and power for heating and cooling. Wire specifications recommend using 18- to 22-gauge thermostat wire. Shielded wire is not required. The common wire is optional when the thermostat is powered by batteries.
