Start-Up, Operation and Service Instructions
SAFETY NOTE
Air-handling equipment will provide safe and reliable service when operated within design specifications. The equipment
should be operated and serviced only by authorized personnel who have a thorough knowledge of system operation, safety
devices, and emergency procedures. Good judgment should be used in applying any manufacturer’s instructions to avoid injury
to personnel or damage to equipment and property.
WARNING: Disconnect all power to the unit before performing maintenance or service. Unit may automatically start if
power is not disconnected. Electrical shock and personal injury could result.
WARNING: Units with LineaHeat use Solid State relays, which generate heat when used. The temperature of the
control box and/or heat sinks may be hot.
OVERVIEW
LineaHeat is an electronic, time proportional electric heat system. The heat output of the heater is modulated utilizing quiet,
rapid performing solid state relays. The relays are switched off and on to allow the heating of electrical resistance elements.
The proportion of time the relay is on dictates the proportion of maximum heat the electric heater can produce. The solid state
relays are switched off and on by a supplied Electric Heat Module (EHM). The EHM accepts an input signal from the terminal
unit controller or thermostat for the amount of heat desired. The EHM can accept a variety of different input signals when
interfacing with controls. The type of input the EHM will accept is modified by changing the position of one or two jumpers
easily accessible on the board.
The LineaHeat is available with an optional discharge temperature sensor. When used with the discharge sensor option, the
LineaHeat will modulate outgoing temperature from the unit between the maximum temperature setting and initial temperature
of incoming air before heating began. The discharge temperature set point is easily adjusted in the field by rotating the
temperature dial on the EHM. The EHM will not allow temperatures over the set point so as to prevent overheating,
stratification, and energy waste from heated air lost through overhead returns.
START-UP
INPUT SETTING. The LineaHeat board is capable of being controlled and operated 7 different ways. The units are ordered
with an LXY code, where “X” is coded for unit power and “Y” is coded for the application. This “Y” application can be
changed in the field. The application desired is chosen by placement of jumpers in the corner of board (See Drawing 1 on page
2). Jumper settings below are representative of pins at bottom left of control board as shown in drawing. Wiring diagrams for
each are on pages 5 & 6.
LX3)
0-10V: This application accepts a 0-10 Vdc (0-20mA) signal to modulate the heater
output. The output is proportional to input signal (i.e., 4.5 volts sets the heater to 45% of
kW rating).
LX2)
2 Stage (2Stg): This two stage application accepts two 24 Vac inputs to step the heater
output from off to 50% or 100% heater kW rating. A signal to “Inc” is 50% and a signal
to “Dec” is 100%
LX1)
On/Off: This application accepts one 24 Vac input at “Inc” to step the heater output from
OFF to 100% heater kW rating. The signal may be pulsed off and on over a small time
period to provide proportional heat. For example, a signal that is on for 4.5 seconds every
10 seconds would produce 45% of the heater’s kW rating.
