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.
This specific model series, HE-A-**-**
This model series is outlet warm air sensing only. With a preset warm air temperature, the electric
elements modulate to maintain this preset temperature based on the sensing of the supply sensor (ST).
The CFM requirement will always have to be setup for full electric capacity.
Make-Up Air Applications
Located on the WarmFlo board (logic controller) is a 40-pin microcontroller chip. On this chip is a white
sticker which indicates chip version (V2.3*) and chip code. This correct chip code for make-up air
applications is
WFMU
which has a specific temperature range options for make-up air applications.
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.
Using a wood boiler with the water coil inlet option is an ideal arrangement.
If using a forced wood system, caution must be used when allowing the wood warm air to enter through
the ECM™ motor blower. The maximum temperature for the ECM™ motor is approximately 120° F.
