The thermostat may be reset with the simple push of a few buttons.

There are just a few quick actions to take, and they are as follows:

  2. Deactivate the thermostat
  3. Take the fuse out for five minutes.

In the event that this does not work, turn off all of the RV’s electricity and attach the 12-volt power supply to the fuse and blue ground wire.

Call a certified technician or the dealer if you are still covered by warranty if that doesn’t fix the issue.

They should be able to reset the device for you, and if the thermostat has a problem, they can also quickly repair or replace it.

Operation of an RV.Comfort.ZC

Avoiding using the high setting is the first stage in the procedure.

If there is a need for heat inside the RV, this option will simultaneously switch on the AC and the furnace.

You should set the device to auto in order to utilize it.

Alternately, you may utilize the set point buttons, which you push after pressing the system button to increase or reduce the temperature.

The system button instructs the appliance to switch on the furnace or the air conditioner.

Even after turning the thermostat off, you can still observe the real temperature of the space.

Once the system is in operation, you go to the mode button to choose how much cooling or heating you want to occur.

Use the zone button and repeat the procedure if you wish to set a different temperature for the next zone or additional zones.

The RV.Comfort.ZC Thermostat Is Produced By Who?

This gadget’s maker, Coleman-Mach, seems to have intended it to have a single use.

By the phrase, it is indicated that you must employ Coleman-Mach equipment exclusively or else undergo extensive rewiring.

The only variation between the 9330-33 variants of this thermostat is the color; all of them will function identically.

Additionally, Coleman advises against building a DIY thermostat.

Any thermostat replacement or installation should be handled by a qualified technician.

You must turn off all power to the device before doing any tasks including removal, installation, or cleaning.

Anytime you are using an electrical equipment, you should do this.

In these situations, safety comes first and restoration work comes second.

If you have any inquiries regarding this thermostat’s functionality or would want assistance troubleshooting it, get in touch with Coleman.

Typical RV.Comfort.ZC Issues

It’s possible that the typical issues you run into are the same ones your friends with non-Coleman-Mach gadgets experience.

The batteries should be examined first.

You’ll have to swap them out if they lose power.

After that, you need to examine the electrical system.

Find any loose, damaged, or frayed wires and fix them in accordance with the issue you discover.

Next, inspect the fuse and the breaker controlling the device’s power supply.

You will need to replace them if they blow out or trip, or you can turn them back on.

A short in the system is often indicated by the breaker tripping.

This is why you need the assistance of a trained specialist to identify and resolve the issue.

There is a brief list of additional typical issues in the handbook that you can encounter.

These are just a few of the possibilities that could present themselves while you are away on vacation.

To assist you in resolving some of these small difficulties, it is recommended to print out or keep a copy of the manual.

Thermostat for RV Comfort.ZC is frozen

The instructions states that while the thermostat is off, the cold and heat modes, and the system setting are all off, you should not be able to adjust the temperature or utilize the temperature buttons.

Check your settings to determine if you unintentionally disabled the thermostat or another feature in order to resolve this problem.

Additionally, the top control board’s settings may not be appropriate for the zone you are attempting to heat or cool.

Signals used for communication have a delay built into them as well.

These issues could apply to you as well, and all they need is a reset or a little patience as you wait for the conversation to conclude.

The best course of action is to do a reset first, as described above, and see if it solves the issue.

If not, you might try contacting a local specialist or the firm that will fix the issue.

The Zones of RVComfort.ZC Won’t Change

Try to reset the thermostat as the standard fix for this issue.

To attempt to fix the problem, adhere to the preceding recommendations.

It may not work, in which case you could have a misconfigured setting in the higher control board.

To enable zone switching, each zone must be linked to this higher control board.

The board is within the air conditioner’s return air plenum.

The zone jumper must then be set to the zone or zones that you wish the control board to control.

If the reset procedure did not succeed, look at the manual’s section on setting up the higher control board.

Before repairing this component, make sure all power is turned off.

Location of the RV comfort.ZC Thermostat Fuse

The fuse should be located below the thermostat’s face plate, claims one RV technician.

A glass fuse should be present when you just snap that off.

The next step is to remove that fuse and, if it has failed, replace it with a new one.

When the face plate is removed, a fuse that resembles a conventional fuse is located in the bottom right-hand corner.

Pull it out of the holder with a screwdriver, then quickly snap a new one in its position before replacing the face plate.
