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.

Page 2: Electrical Requirements
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. -
Page 3: 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. - Page 4 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.

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 Locate the appropriate location where this element will temper all the air going to the room registers or distribution ducting. -
