The Rite-Temp Climate Control Unit (CCU) developed by Lubrication Specialist is comprised of an Espar coolant heater, a Bergstrom AC unit, four deep-cycle Discover® Dry Cell batteries and a battery box that is mounted in the truck frame behind the sleeper. The AC unit (not shown) is mounted under the bunk.
Summary of Operation
The Rite-Temp CCU utilizes only the auxiliary batteries during “no idle” times; this means that fully charged starting batteries are always available.
When the truck is not running, the battery separator disconnects the auxiliary batteries from the starting batteries. Upon startup, the voltage rises to 13.2 volts; the battery separator closes, and the truck‘s charging system charges the auxiliary batteries.
Normally an ignition key is necessary to operate the sleeper fan blower. With the Rite-Temp CCU, the sleeper climate controls automatically switch over to the auxiliary batteries for power when the auxiliary heat switch is in the “on” position.
Operation of the Rite-Temp CCU in the cooling mode is very simple. Since the Bergstrom unit is not intended to cool down a hot sleeper but is meant to maintain an already cool sleeper, it is important before shutting off the truck‘s motor to turn the Bergstrom to the “high” position, close the curtains and cool the sleeper down using the truck‘s A/C. Once the sleeper temperature is at the desired temperature, the motor should be turned off.
Operating the Rite-Temp CCU in the heating mode is just as easy for keeping the sleeper, motor and fuel warm. While the auxiliary heater is on, it is using electricity only from the auxiliary batteries. After the truck is parked, the motor should be turned off and the auxiliary heat switch set to the “on” position. The blower speed and temperature should be adjusted on the sleeper’s climate control panel to the desired position. Once on, the auxiliary heater water pump will activate and circulate the hot water that is already in the motor‘s cooling system. This utilizes the heat that is already built up in the motor.
Depending on outside temperature and wind, as much as four to five hours of usable heat may be used before the Espar heater activates. Once the water temperature drops to 120 degrees, the Espar coolant heater will come on automatically to maintain coolant temperature, and the auxiliary fuel pump will start automatically. The pump draws warm fuel from the motor‘s coolant-heated fuel filter and returns it back to the tank. This keeps the fuel warm and helps prevent “waxing” during extreme cold conditions. 
The Rite-Temp CCU provides A/C cooling of the sleeper when it’s warm and heat for the sleeper motor and fuel when it’s cold. The unit is encased in a compact frame and utilizes four Discover® group 31 batteries with 140 amp hours each, for a substantial total power capability of 560 amp hours.
The Discover battery represents the latest in dry cell technology and has more amp hours than any other group 31 battery. With a three-year warranty and the first 12 months free replacement, that means less maintenance and less operating cost than any other APU (auxiliary power unit) on the market. This also means a faster ROI which typically is one year.
