WARMFLO

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.

INSTALLATION REQUIREMENTS 1. 2. 3. 4. All installation work must be performed by trained, qualified contractors or technicians. Electro Industries, Inc., sponsors installation and service schools to assist the installer. All electrical wiring must be in accordance with national electric codes and local electric codes, ordinances, and regulations. Observe electric polarity and wiring colors. Failure to observe could cause electric shock and/or damage to the equipment.

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.

. 6. 7. 8. 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). 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).

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. B. C. Extend HP reversing valve wire to the designated “RV” tab. If the heat pump logic is “logic high” for heating, cut the W1/W2 resistor on the control board with a side cutter. The location of this resistor is shown below.

OPERATIONAL TIPS Comfort Level Temperature Setting The inside circuit board contains a screwdriver switch setting marked Ø through 9. This is usable only for Ø through 7. Unless otherwise specified during the time of order, this unit is equipped with a default “D” chip. This is a broad range temperature with settings at 12° steps. If you would like a more precise temperature setting, the “plug-in chip” can be changed for a temperature range selection.

Sequence (10KW) A - D. Same as above. E. If element #1 is on for 10 min. (LED constant), element #2 turns on. 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.
