Digital Dometic Duo-Therm Brisk 3-button thermostat kit. Replaces digital or analog RV thermostats with heat-pump option on many Dometic Duo-Therm air conditioners. If your RV or camper has one air conditioner with a 6-pin plug and has a heat pump (NOT a heat strip) and perhaps a furnace, then this kit will work for you. A heat pump is different than a furnace. A heat pump is found inside your a/c and extracts some heat from the cold outside air. A furnace is a separate heating unit. Your RV could have both.
If your a/c does not have a heat strip or heat pump, then order thermostat kit number 3313189.000 or 3313189.015. If your a/c has a heat strip, then order thermostat kit number 3313189.049 or 3313189.056.
This kit includes a white 3313193.000 digital thermostat, 3313269.000 relay box, freeze control sensor wire, an outside thermostat wire & mounting screws.
Technician note: If you are replacing an older analog thermostat, this digital unit will replace the analog thermostat but you must install the relay box included with this thermostat. This kit will operate most any single Dometic Duo-Therm air conditioner with a 6-pin plug and heat pump, and a furnace. Before ordering be sure to identify the wires. View the pictures to know which wires you will need to identify to hook into the relay box.
Your new thermostat only needs 3 wires. Since most analog thermostats use more than 3 wires, we get a lot of calls asking which wires are hooked into the new thermostat. Included with the relay box is a 4-wire harness. Three of those wires will connect to your new thermostat. Wire-nut those three wires to three of your existing thermostat wires and mark those wires at the thermostat end. Ignore the other unused thermostat wires. Of the old wires leading to your old analog thermostat, it doesn't matter which three wires you choose.
If you are not sure if your A/C and furnace will adapt to this relay kit, then e-mail us the following: pics of your a/c wiring, your a/c model number, pics of your furnace wiring, your furnace make and model number. Please do not call until you have first e-mailed us the information we've asked. A service charges may apply if you call and are not prepared. You can e-mail them directly to Mark at email@example.com.
Kit contains a freeze control sensor and an outside temperature sensor. Place the freeze control about an inch into the fins of the evaporator coil as explained in the enclosed instructions. The sensor will help keep your unit from freezing up. Place the outside temperature sensor outside as this shuts off the heat pump if temperatures get too cold.
NOTE: If you install the thermostat and it still acts up, then perform a system initialization by following these steps:
Press and hold the '+' button.
Press and hold the 'On/Off Mode' button.
Hold both buttons down for about three seconds until the screen shows a -- --.
Release both buttons and press the 'On/Off Mode' button again to turn system off.
Press 'On/Off Mode' to turn back on. The thermostat has now been reset.
For a replacement thermostat only, see wall thermostat part # 3313193.000 or 3313193.017.
