Congratulations on your purchase of a PROHEAT X30 diesel-fired heater. This handbook is provided to
summarize the operation and maintenance of the PROHEAT X30 for the Owner/Operator.
For complete information, please refer to the Installation and Service manual SL9211 at www.proheat.com
Although trucks have been used throughout this book, applications for PROHEAT are by no means
limited to trucks. PROHEAT heaters are designed to be used on any diesel equipped vehicle
including: trucks, buses (school, transit and coach), construction equipment, off road equipment,
military equipment and cargo.
PROHEAT heaters are used in the following applications:
• Preheats an engine block to ensure reliable cold weather starting.
It is recommended that PROHEAT is used year round (winter and summer) to reduce engine
wear associated with cold starting.
• With the engine off—supplies heat to the engine and sleeper for comfort and reduced idle time
resulting in cost savings through reduced fuel consumption and engine wear.
• With the engine running—adds heat to the coolant system when the engine does not provide
adequate reject heat for the vehicles interior.
• Provides heat to protect cargo from cold weather damage.
• With the engine off - supplies minimal heat to prevent freezing over long periods of time.

Your PROHEAT X30 is controlled by either an ON/OFF manual toggle switch or by an optional
PROHEAT 7-day timer. The timer can be controlled manually, or it can be set to start at a predetermined
time. Both devices have a light that indicates when the heater is operational as well as flashing to indicate an
error state
. Your installer may have enabled optional features and heating modes. Please see the X30
Installation and Service manual SL9211 at www.proheat.com or your Dealer for more information.
1. SWITCH ON – The ON/OFF switch (or Timer) lamp and the Proheat Control Module (PCM) “ON”
LED will light. In addition, the Hour Meter (Auxiliary Output) will be powered. If the coolant
temperature is below 150°F (65°C) the PROHEAT enters Pre-check. If the coolant temperature is
above 150°F (65°C) the PROHEAT enters Standby.
2. PRECHECK – The PCM performs a short diagnostic cycle. This takes a few seconds to check
components for proper ranges, short-circuits and open circuits. If there are no errors indicated,
the PROHEAT goes to “Ignition”.
3. IGNITION –
The blower starts first, followed by the coolant pump, ignition spark, air compressor and
fuel pump. The ignition electrode sparks for up to 60 seconds. Once a good flame is detected, the
PROHEAT goes to “Full Output”.
4. FULL OUTPUT – The PROHEAT runs at Full BTU Output until the coolant temperature reaches
185°F (85°C) at the heater outlet. If the time to heat the coolant to 185°F (85°C) is longer than
10 minutes the PROHEAT then shuts the flame off and goes to “Cool Down” (Purge). If the time to
heat the coolant to 185°F (85°C) is shorter than 10 minutes the heater will slow down and reduce
the heat output for the remainder of the 10 minutes.
5. MODULATING BTU OUTPUT – The PROHEAT may reduce the heat output up to 50% automatically
once the coolant temperature reaches 185°F (85°C) at the heater outlet.

The heating cycle will end once the 10 minutes have past OR the coolant temperature reaches
194°F (90°C) at the heaters outlet.
The PROHEAT then shuts the flame off and goes to “Cool down” (Purge).
6. COOL DOWN (Purge) – The air compressor and fuel pump shut off immediately. The blower
and coolant pump continue to run. After 3 minutes, the blower stops and the PROHEAT goes
to “Standby.”
7. STANDBY – The coolant pump circulates the coolant through the system until the temperature
drops to 150˚F (65˚C) at the heater outlet; then it will enter Precheck and repeat steps 2 to 6. The
PROHEAT will continue to repeat steps 2 to 5 until it is switched “off.”
8. SWITCH OFF – If PROHEAT is in Full Output, it will Cool Down (Purge) first, then shut “OFF”.
If PROHEAT is in Standby, it will shut “OFF” immediately.
When switched OFF, the Sleeper Fan (if equipped) output turns off.
When switched OFF, the Hour Meter (Auxiliary Output) will shut off.

X30 Owner’s Handbook Page 7
Optional Sleeper Fan Operation
Today’s sleepers are designed for maximum comfort for the vehicle operator. Generally the units are
larger and have accessories that compete for battery power with auxiliary heaters. PROHEAT is a
cost-saving component by reducing fuel consumption and engine maintenance. Therefore, it should
be given priority over these accessories.
PROHEAT installation recommendations are designed to allow the operator to:
• Run the PROHEAT with the vehicle ignition key in the OFF position
• Set the desired sleeper ambient temperature using the dedicated Proheat thermostat
The vehicle operator’s responsibility is to ensure that:
• Coolant valves used in the heating system are open: These can be manually or electrically
operated (electrically operated valves must be opened before shutting the vehicle OFF)
• When operating the PROHEAT, power consuming accessories such as refrigerators, DVD’s, TV’s,
satellite receivers, heated mirrors, etc. are not used to ensure enough starting current for the engine
• Sleeper curtains are closed: The PROHEAT is designed to heat the sleeper and engine as efficiently
as possible – heating the cab, fuel tanks and batteries means longer run time which will require
more battery power

The PCM (PROHEAT Control Module) has self diagnostics for reliable operation, safety and protection
of the PROHEAT. If a problem is detected it shuts the PROHEAT OFF and will start blinking the
diagnostic indicator light on the PCM cover, toggle switch, timer red manual light or OEM indicator
light (installation options). A diagnostic code number is also displayed on the PCM Diagnostic Panel
located under the PCM cover and the optional PFC.
PROHEAT will attempt one (1) re-start after a Function or Component Diagnostic Code has been
indicated. The re-start will not occur during a Cool Down (Purge) cycle or if the coolant temperature
is above 150°F (65°C). ALWAYS let the PROHEAT attempt two (2) starts so that the PCM can point
you to the problem area.
1. Switch the PROHEAT ON using the toggle switch, T-II Timer or PFC.
2. Check the diagnostic code indicator located under the PCM cover on the heater. The codes are as
a two digit code followed by a dash single digit code such as 01-1.
3. Function Diagnostic codes 01 to 05 are usually caused by vehicle system interface problems.
4. Components Diagnostic codes 13, 14, 19 and 21 to 29 indicate an electrical problem ONLY, with
PROHEAT components, wiring or the PCM. Refer to your Installation and Service manual SL9211
for further information.
