Digital Dometic Duo-Therm Brisk 3-button thermostat kit. Replaces many analog RV thermostats on many makes and models of air conditioners. Will operate most furnaces and one air conditioner (without heat strip) from a single digital wall control. Kit includes 3313192.000 digital thermostat, 3313191.000 relay box, freeze control sensor wire, power wire & mounting screws.
This kit may also be adapted to other brands and models of RV a/c units by purchasing harness part # 3313. If you have a Duo-Therm Dometic air conditioner with a 6-pin female molex plug, you will not need to order this harness. If your existing air conditioner does NOT have a 6-pin molex plug, identify that you are able to access the following 5 wires: 120V white common, 120V black line, green or yellow ground, high black fan speed and a low red fan speed wire coming from your air conditioner. If you have identified those five wires coming from your air conditioner, then you can probably adapt this kit by ordering harness part # 3313. Wire colors may differ.
Technician note: As analog thermostats are quickly becoming obsolete, 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 air conditioner and furnace but 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. If your existing A/C unit does not have a 6-pin female molex plug, you will need to order harness #3313 to adapt this box to your A/C assuming you have correctly identified all the wires as listed in previous paragraph. Wires incorrectly hooked up will instantly void your warranty. Believe us, when we get the relay box back we can tell which wires were hooked up wrong by which components inside the box are burnt up.
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.
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 firstname.lastname@example.org.
Kit also contains a freeze control sensor that's used in models 4579, 4591, 4595, 579, 590, 591, 595, 600, 630, 640 & 650. Actually the freeze control sensor will work with any a/c. Just place about an inch into the fins of the evaporator coil as explained in the enclosed instructions. The sensor will help prevent your a/c unit from freezing up. Remember, if freezing up is a constant issue, call a service tech to have the problem diagnosed and fixed.
Kit replaces Dometic part # 3107541.009, 3107541.017, 3107541.025, 3107546.008 among others.
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.
