DC mode

RM2354, RM2454, RM2554 & DM2663

When operating in DC mode (3-way models only), the DC mode indicator lamp is illuminated and all other lamps are off. To select another operating mode, turn off the DC mode by pressing the DC selector button. The DC lamp is turned off.

When there is no charging of the house battery, switch to AUTO mode or GAS mode since running the refrigerator on 12 V DC will quickly drain the battery.

Limp mode of operation

In the event of a failure of a major operating component, the control system will continue to operate the cooling system.

RM2351, RM2451, RM2551, DM2652 & DM2852

If the control can not read the temperature sensor and control the preset temperature, the control will run the cooling unit continuously at the energy source available. The refrigerator will continue to operate in this mode indefinitely - or - until a new sensor is installed and the system reset.

Two modes of operation can occur:

1)The first limp mode of operation will execute if the display module becomes non functional. The control system reverts to full automatic operation selecting the best energy source available with AC, DC (3-way only) and GAS priority. The temperature setting is maintained at the mid position. The power module will continually attempt to reestablish opera- tion of the display module.

2)The second limp mode of operation will execute when a failure of the temperature sensing device or associated electronic circuitry occurs. If this should happen, the con- trol system operates on the energy source selected via the control panel. The cooling unit runs continuously on the se- lected energy source. The refrigerator continues to operate in this mode indefinitely or until a new sensor is installed and the system is reset.

Climate control system

DM2652, DM2662, DM2663, DM2852, DM2862, DM3862, NDM1062 & NDR1292

During the summer months of high temperatures and humidity, the metal frame between the freezer and fresh food compart- ments may have water droplets forming. The number of water droplets will increase if the vehicle is not air conditioned dur- ing these months. The refrigerator comes standard with a 12 V DC climate control that will evaporate the water droplets when they form. The climate control can be left on continuously or used only when temperatures require it. Note that when turned on, the climate control will draw 12 V DC power continuously. Turn it off when a charging source is not available.

Low ambient control

DM3862, NDM1062 & NDR1292

The refrigerator is equipped with an exclusive feature that allows for trouble-free operation in low ambient temperature (like below 50°F) for extended periods of time. Once the out- door temperature is above 50°F, the low ambient switch should be turned off.

Thermostat

RM2354, DM266, DM2663, DM2862, DM3862, NDM1062 & NDR1292

The thermostat controls both the gas and electric operation, thereby eliminating the necessity of resetting each time a dif- ferent energy source is employed. After the initial start-up, the thermostat should be adjusted to the desired temperature setting.
