Electric Heat Control
1. Electric heat control can be factory configured for either
on-off or analog control.
2. On-off control requires a 24VAC signal applied to
terminal EH 24+ to cycle the electric heat elements.
3. Analog control uses an SCR control module to power the
electric elements and requires a 0-10VDC signal applied
to terminal EH 0-10V, to modulate heat output.
Valve Control
1 Valve control can be factory configured for either on-off
or analog control.
2. On-off control requires a 24VAC signal applied to
terminal VLV1 24+ or VLV2 24+ to control the valve.
3. Analog control requires a 0-10VDC signal, applied to
terminal VLV1 0-10V or VLV2 0-10V to modulate the
valve.
Motor Controls
1. Unit sizes 006 – 020 ship with an EC motor factory
configured for either three speed or analog control.
2. The three speed control option provides three separate
field adjustable motor speeds that can be activated by
applying a 24VAC signal to the appropriate terminal. This
allows fan control with a conventional three position fan
switch or fan coil style thermostat. The speed terminals
in the unit, CALL 1, CALL 2, and CALL 3 correspond to
the low, medium and high speed terminals on the switch.
Speed adjustment is made at the EVO board by turning
the dial adjacent to the speed terminal to change the
motor's RPM for that speed.
3. The analog speed control option requires a 0-10VDC
signal applied to terminal FAN 0-10V on terminal block
TB4 to control motor RPM. 0.0VDC turns the fan off.
1.0VDC is the threshold for turning on the fan and
induces the minimum motor RPM. 10.0VDC runs the
motor at maximum RPM.
