The following information is provided as recommended language for developing your procurement
specifications. The information can be printed or saved to your computer for further modification.

Teleflex Proheat M Series M 50
5.4.8.7   Supplemental Heater
If an auxiliary heater is required to maintain temperature in the passenger compartment and/or provide
engine preheat the bidder shall supply a PROHEAT M 50 series 50,000 BTU auxiliary heater.
The heater should be equipped with an electronic Heater Control Module (HCM) with a built in
microprocessor that incorporates circuit monitoring and protection. The HCM shall provide for a remote
LED display for major heater components and specific system functions for supplying self-diagnostic
information. The HCM shall provide internal voltage regulation to maintain constant motor RPM. The HCM
shall be equipped with a memory function that records intermittent fault codes for retrieval with the
manufacturer’s diagnostic data link kit. The HCM shall also incorporate a soft start feature that utilizes solid
state switching with controlled motor acceleration. (Relays are not acceptable)
All motors used in the heater system must be provided with fully sealed bearings. The heater shall be
programmed for 24-Volt power. The heater shall be equipped with a seal less; magnetic coupled coolant
pump offering 8 gallons per minute minimum flow. All electrical connectors shall be water tight and
corrosion resistant. The heater shall be plumbed to circulate coolant directly to and from the engine. This
coolant loop shall allow for rapid engine preheating and optimum coolant flow at all times. The auxiliary
heater shall carry a two-year warranty on parts and labor. The auxiliary heater installation shall require the
approval of the Proheat technical service manager. The OEM shall locate and wire a remote diagnostic plug
for the heater diagnostic tool in an area easily accessible for the mechanic. This plug should preferably be
located in the driver’s area near the engine and transmission diagnostic plugs.

Heater Operational Options:
Option 1:
Programmable Timer. The heater system shall be equipped with a digital timer (location, at the discretion of
the authority), allowing flexibility in programming that can be set for 5, 6, or 7-days. The timer shall be
equipped with operation indicator lights and offer a two set option to start the heater in preheat mode to
warm the engine before starting.
Option 2:
Manual Timed Mode. The heater shall provide a manually timed input connection on the HCM to be used
with a momentary toggle switch (location, at the discretion of the authority) that enables the Proheat 90
minute preheat mode.
Option 3:
Supplemental Mode. The heater shall provide a supplemental input connection on the HCM that receives a
signal from the vehicle system that enables the heater whenever the engine is running. A mechanics disable
switch shall be provided on all circuits that automatically activate the heater. This to be used to disable the
heater when the coach is being maintained, serviced or for such periods that the heater is required to be
deactivated.
