Installation Setup
There are specific peg jumpers relating to cooling tons, heating kW, heat pump reversing valve logic, and
thermostat type. These must be properly evaluated and selected to match
each
installation.
The “setup or programming” section has all the detailed instructions and selection tables.
The WarmFlo controller also has various dial switch selections relating to duct temperature set point,
minimum warm air set point, HP compressor ODT shutoff temperature, and ramp up efficiency dial.
These are standard WarmFlo technology and setup requirements, if you’re not familiar with WarmFlo
controller study the HD320 WarmFlo information document, also in this package.
NOTICE:
When changing any setup jumpers, power down and up. ECM™ motor needs 240V power
and control power removed to
reset
and reread specific control lines. Open CB number 1 for 10 seconds.
Operation Instructions
The “Operation Indicators” section contains information relating to LED monitor lights, thermostat
sequences, etc.
Installation Checkout
Attached to this manual is a warranty certification and checkout procedure. This must be completed and
returned for warranty coverage. This is the responsibility of the contractor or company which “sold the
job” and is assuming responsibility to the end customer.
Warranty Statement
See the last page of this manual for detailed limited warranty coverage explanation.
Application
General
The configurator, previous page, details several product types. Re-verify nameplate on your received unit
to make sure it properly represents the product type you need for your installation/application.
The setup control board jumpers provide ECM™ blower motor speed flexibility to match the model and
your heat/cool size requirements.
When using with heat pump, must use HE-H Series. Because of WarmFlo’s sensor action and control,
the heat pump coil must be at the inlet side of the blower.
This specific model series, HE-H-**-**
Full WarmFlo capability with outdoor sensor. This provides warm air outlet temperature dial selection
and supply air ramp up with the decrease of outdoor temperature. This WarmFlo feature definitely
applies to heat pumps, but it is also the top of the line comfort for straight electric, with air conditioning.
The warm air dial suggested setting is 96° or 100° and the front dial selects the rate of ramp up or
temperature increase based upon outdoor. The “C” setting will provide 114° warm air at 0° or 125° at -
20° F outside. The ECM™ blower also ramps up in speed as there is an increase in supply temperature or
decrease in outdoor temperature. Depending upon setup selection, the moderate heating blower speed
could be as low as 50% of full capacity and full capacity blower is only used below 15° outdoor.
Backup or Assist Wood Heating
This WarmFlo Electric Furnace is ideal for accompanying a wood heating system. The WarmFlo
technology and sensors will determine the Btu/h heating requirement of the building. If the wood warm
air is below the requirement, a small portion (or as required) of the electric elements will come on
automatically supplementing the wood heat.
