COMFORT MODULE
Specific Application
Air exchanger, temperature boost
Make-up air
Temperature comfort boost
Air source HP comfort boost
Comment
This module is a heating element and controller to “temper” the supply air and bring it to a
comfortable level. For general duct temperature boost or heat pump comfort, this unit raises
the warm air supply temperature to the set point temperature value desired. In the make-up
air application the supply or inlet is actually outside air. This unit contains a built-in
controller with duct sensor to modulate the electric element (part of this unit) using only the
required electric energy to reach comfort level. This is more than basic on/off.
This is a single (duct temperature) WarmFlo sensor product. If you need the outdoor sensor
WarmFlo controller, call factory for other models.

GENERAL
This is a completely functional electric heat element package with the built-in WarmFlo, duct sensing,
controller. It is installed in the main distribution duct or external to the heat pump unit/air handler.
This module can be installed upflow, downflow, or horizontal. However, it must always be on the
warm air side of the HP coil.
If you desire the outside temperature sensing WarmFlo Smart Controller with its various application
modules (total electric, dual fuel, HP add-on, load management, etc.) this is the wrong product. Call
the factory for further WarmFlo information.
Purpose
When comfort level requires a slight increase in the heat pump air delivery temperature, this module
“tempers” the warm air by raising the warm air temperature a very small number of degrees to produce
comfort level.
Concept (Heat Pump Application)
1. One piece unit, including the electric element.
2. No outdoor sensor.
3. Modulates its own electric element, based upon remote duct sensor and installer set comfort
level temperature.
4. Totally external to the heat pump air handler product.
5. Existing or standard heat pump room thermostat, air handler, strip heat, compressor, etc.; all
remain without modification or functional change.
6. Anyone can install (non HP trade).
7. Adds the comfort level increase in temperature whenever the compressor is on (roomstat
stage 1) and before roomstat stage 2 activates strip heat.
8. Electric element power usage is controlled by duct sensor and comfort level. Electric
element Power is not wasted or turned on in banks.
9. Does not necessarily add to the building service panel loading because as soon as the normal
strip heat turns on (stat stage 2) and raises the temperature, this unit automatically shuts off.
10. Internal logic or chip begins with reset at each “Y” heat call.
ELECTRICAL REQUIREMENTS
EM-WC0515* – 30A Panel Breaker, 20A Nominal Amp
EM-WC1025* – 60A Panel Breaker, 40A Nominal Amp
* H = 10” long element; L = 16” long element
208 Volt application – the elements within the standard product are rated a 240 volts. If operating at
208, there will be approximately 25% reduced capacity. The internal transformer may or may not
adequately operate the control system from a 208 source. Voltage measurements between “R” and
“C” must be 22VAC or greater when the system is in the complete operational mode.

04/27/2021 2 HI326
INSTALLATION REQUIREMENTS
1. All installation work must be performed by trained, qualified contractors or technicians.
Electro Industries, Inc., sponsors installation and service schools to assist the installer.
2. All electrical wiring must be in accordance with national electric codes and local electric
codes, ordinances, and regulations.
3. Observe electric polarity and wiring colors. Failure to observe could cause electric shock
and/or damage to the equipment.
4. This unit can only be used for its intended design as described in this manual. Any internal
wiring changes, modifications to the circuit board, modifications or bypass of any controls, or
installation practices not according to the details of this manual will void the product
warranty, the ARL certification label, and manufacturer product liability. Electro Industries,
Inc., cannot be held responsible for field modifications, incorrect installation, and conditions
which may bypass or compromise the built-in safety features and controls.
HEAT PUMP INSTALLATION – AIR FLOW REQUIREMENTS
Since this is a heat pump application and since this is typically a “temperature boost” electric heating
unit, it is assumed the heat pump air handler capacity is larger than the basic requirement of this
product. But as a verification, the minimum airflow required by this product is:
EM-WC0515* 1000 CFM
EM-WC1025* 1500 CFM
This unit is installed in the warm air, discharge, plenum of the heat pump air handler or in the plenum
above the A-coil (typically two units, one on each side). In all cases it must be external to the heat
pump cabinet. The location within the plenum is determined by the following requirements:
1. Before any horizontal distribution duct, elbows, tee, etc.
2. Maximum practical distance from the HP air handler, but meeting the requirements of paragraph
1 above.
3. If the plenum is a straight discharge (no elbow, obstruction, tee, etc.) from the HP air handler,
National Electric Code paragraph 424-59, four ft. rule, does not apply.
4. If the plenum is larger than 12” x 12” and there is a need to install this unit closer than 18 inches
to the HP air handler discharge blower, call the factory for special baffling instructions.
5. HP air handler discharge blower – attempt to center the electric elements in the plenum and with
the maximum practical distance from the blower discharge.
6. Above A-coil – typically one on each side, angled such that the discharge air from each A-coil
“slab” goes through the element rack. Typically the heat pump airflow is significantly greater
than required by these boost inserts (electric insert is typically small in capacity); therefore,
baffling is not required, simply locate so the majority of the A-coil discharge air goes through
the element rack.

CLEARANCE – DUCT SURFACE AREAS, DUCT INSTALLATION, ETC.
When installed within air handler plenum or furnace/A-coil plenum, the codes and rules relating to
clearance apply.
When installed in an “inline” duct or round pipe adapter for a general distribution boost heater or air
make-up application, observe the following guidelines:
1. This product must be installed in a metal duct, size of the element rack.
2. There shall be no insulation on the inside of this sheet metal duct section.
3. Any flex-pipe or other insulated pipe must be at least 24” from the electric element.
4. Mounting – there must be at least 2” air clearance around all sides of this sheet metal duct section.
5. If there is a need to insulate this duct section for moisture condensation or in an unheated
compartment, it is permissible to wrap insulation around the exterior of this metal duct section.
6. The control box must be positioned so it will not receive water dripping or collection of moisture.
7. See next section on duct sensor installation.
BOOST HEAT INSTALLATION
This section applies to any warm air duct or inlet/outlet of an air-to-air (HRV) heat exchanger. Also
can be applied for fresh air inlets such as hood vents, small commercial fresh air, make-up air, etc.
Duct size needs to be approximately the size of the electric element rack. If the duct is more than
approximately 2 inches larger for either depth or width, baffling is required. See drawing HH313 for
the single element product or HH315 for the dual element, 10KW product.
1. Air-to-air heat exchanger – install the electric element rack within the discharge duct of the heat
exchanger.
2. Distribution duct, boost heater – install the electric element rack within the air flow duct,
locating a position to cause a majority of the forced air through the electric elements. If the
distribution duct has a depth of 16” or more, we strongly suggest using the “L” model with the 8”
x 16” element rack.
MAKE-UP AIR
Typically in this application outside air enters the inlet and this module gets used to bring up
the mechanical ventilation temperature. You will probably want to use “C” chip, see next
page. Use the following chart to provide additional temperature rise information.

TEMPERATURE RISE COMMENTS
Typically the maximum temperature rise for this product is 40°F for room air inlet or 20°F for
elevated supply temperature from a typical heat pump.
If it is air make-up, outside air, larger temperature rises are permissible, see table above.
INSTALLATION
1. Locate the appropriate location where this element will temper all the air going to the room
registers or distribution ducting.
2. Cut an 8.5” x 2” slot in the warm air plenum/duct.
3. Control box orientation is not critical.
4. Install duct sensor 2 to 4 air flow feet on the warm side of this module. Select a location where
there is good air mixing.
5. Locate the 24 volt control system “common”. Depending upon heat pump manufacturer, this
could be a “C”, “X” or in some cases “B” screw terminal (probably black or blue wire).
Connect the black (18 gauge) control wire to this common point (this is a “tap” connection).
6. Locate the 1st stage call for heat or compressor turn-on wire. This is typically “Y” terminal
(yellow wire). Connect the yellow wire to this terminal (this is a “tap” connection).
7. From the electrical panel breaker specified above, extend the 240 power to the bottom right
control box compartment and connect as standard 240 volt L1 and L2 power wiring.
8. This power wire must contain a copper safety ground, terminate with green wire.
DUCT SENSOR
This unit is equipped with a remote temperature-sensing probe. This is a solid state probe (actually mini-
micro computer chip at the end of the probe), handle with care.
Suggested installation is in the main warm air stream approximately 20 to 24 airflow inches away from the
electric element. Simply drill a ½” hole in the duct, insert probe, and screw in place.
This duct sensor has a 6-wire cable, coil and tie excess. It should be connected to the Red, ST, and COM
screw terminals. The “OT” screw terminal is not used for this product application.
WARNING
IF THE BLACK AND RED SENSOR WIRES ARE CROSSED OR INCORRECTLY INSTALLED AT
THE TERMINAL BLOCK AND POWER IS TURNED ON, BURNOUT DAMAGE CAN RESULT
WITHIN THE SENSOR PROBE.

04/27/2021 5 HI326
ELECTRICAL HOOKUP
240-volt source – from the model number and nameplate determine KW size and amp draw.
According to local codes, building type, wiring length, etc. use appropriate wiring conductor size and
source circuit breaker. Connect to the pigtail wires or terminal block.
Grounding – route and install appropriate size ground conductor between the ground lug and the
building service panel ground bus. This must be a conductor size according to the total amp rating of
the appropriate unit. Conduit is not an adequate ground conductor.
Operation – this unit “turns on” or heats when 24 volts are applied to the yellow and gray wires. Via
an external 24-volt transformer or an external transformer applying 24 volts through a contact (airflow
switch, thermostat, heat pump “Y” wire, etc.) arrange your control circuit to apply 24VAC power
when you want boost heat.
SUMMER OR COOLING DISABLE
This module must be disabled during the cooling cycle to prevent adding heat to the air conditioning
operation.
Select one of the following 3 installation techniques or methods
A. Extend HP reversing valve wire to the designated “RV” tab. When J4 jumper is in place,
a 24VAC input on the RV tab will disable the elements. Review your heat pump’s
installation manual to make certain of your heat pump’s reversing valve logic
B. Add a manual (summer) disable toggle switch between “R” and “RV” tab.
C. Simply turn off 240V breaker during the cooling season.
Method B or C should be used for boost heater applications.

Function
1. Electric element power is only used if the heat pump warm air temperature drops below the
above selected setting.
2. Assuming the heat pump warm air temperature is below this setting, the duct sensor sends a
signal to the internal circuit board requesting a boost in warm air temperature.
3. The built-in controller begins pulsing the electric element to add this temperature. The inside
monitor LED indicates the pulsing duration and the electric element is turned on whenever the
LED is on.
4. Except for the LED and/or clamp on amp meter monitor, there are no other indicators or
troubleshooting aids.
5. See previous section titled “Summer or Cooling Disable”.
Option
This unit can be used as a 5Kw duct heater for room stat, second stage operation.
Internal to the circuit board is a “W” terminal. Connecting roomstat second stage heat function to this
“W” terminal causes full electric element turn on (by-pass duct sensor).
Utility Company Load Control Requirement
Arrange wiring so load control receiver interrupts the yellow or “Y” input. If the yellow wire is
connected to the heat pump first stage Y function, the load control receiver is before this yellow wire
connection and the outdoor unit yellow wire.
Checkout and Calibration
There are no field calibration or adjustments.
Total element turn on can be accomplished by jumpering system “R” (24 volts) to “W” internal
terminal. In essence, this bypasses the temperature modulation function and causes the element to be
full on. However, see previous section “Summer or Cooling Disable”.

04/27/2021 7 HI326
MONITOR LIGHTS
The green LED on the circuit board indicates power at the electric element or modulation of the
electric element. In other words, when the LED is on, full power is at the electric element.
Sequence
A. Electric element is on for 10 seconds after the application of 24 volts AC between yellow and black
wire.
B. Electric element turns off if the temperature is above the warm air set point.
C. If the temperature drops, the electric element modulates to bring it back to the desired temperature
level.
D. If the electric element is fully on (LED on constant) this unit cannot make up the air temperature
required between the duct inlet air and the temperature set point at the sensor probe.
TROUBLESHOOTING
A volt/ohm meter is required for proper diagnosing. A clamp-on amp meter is also very helpful.
1. Green LED 1 flashing two pulses every two seconds – indicates control board cannot read
temperature sensor. Verify temperature sensor connections. If secure, replace sensor.
2. No Heat –
Green LED 1 off:
a) Verify temperature set point. If incoming air is higher than set point, element remains off.
Adjust temperature set point to a higher setting and verify element comes on.
b) If incoming air temperature is less than set point, disconnect the red/black/white sensor wires.
1)If unit starts heating and green LED 1 on pulsing, replace temperature sensor
2)If green LED 1 remains off, replace control board
Green LED 1 on:
a) Verify incoming 240 volts power. 24VAC control voltage is typically sourced separately
from the 240 element voltage.
b) Verify 240 volts across element terminals.
1) If 240 volts is present, shut off 240V and disconnect element wires to verify element
resistance. A good element is approximately 10 ohms each.
2) With 240V incoming and if no 240 volts directly across the elements check the
following points referencing UAW890 or UAW892 depending on your model:
a) Measuring across limit switches, 0v (closed) limit is okay. 240V (open) limit is bad
or sensing over 118° or 150°. With power disconnected check ohms when limit is
room temperature. OL means bad limit.
b) Solid state relay (SSR) 4-wire – check for 240VAC across terminals (3, 4) and (1, 2)
1) 240V measured between terminals 3-4 and 0V measured between terminals
1-2 indicate the solid state relay is good.
2) 240V measured between terminals 3-4 and 240V measured between
terminals 1-2 indicate the solid state relay is bad.
c) Mechanical K1 relays:
1) 240V measured across coil and 0V across contacts indicates relay is good.
2) 240V measured across coil and 240 across contacts indicates relay is bad.
d) If there is no control voltage present at SSR or K1 with green LED 1, replace
control board.
3. Not enough heat:
a) Check amp draw. Approximately 10 amps per element means full power output.
b) Verify CFM and temperature rise. High CFM will result in low temperature rise. Cold
incoming air will be warmed based on the CFM Temperature Rise Chart in attached
document EL907.
