OPERATION AND INSTALLATION
INSTRUCTIONS
INSTALLATION:
OPERATION:
Two settings on the display are available. The minimum fan
speed can be set to match the idle capability of the fan
controlled by the PEC-1 control. The desired room static
pressure is set to establish the control logic for pressure
control.
The first LED "NEG" on the display lights to indicate a
negative pressure reading or setting. The pressure display
is divided by 1000, for example, if the display indicates 080
and the led NEG is lit , the real value is -0.080 IN WC The fan
speed will display as a percentage.
As the control fan speeds up and slows down to
compensate for changes in room pressure, the actual fan
speed as a percentage can be displayed. Changing the
desired room static pressure will also cause the fan to
change speed to adjust for the different pressure settings.
DIP switches settings:
DIP #1: Not used
DIP #2: ON - Exhaust mode
Increases output when pressure decreases
SPS-1 Static Pressure Sensor
The SPS-1 static pressure sensor can be installed up to 500
feet from the PEC-1 control unit. A three-wire cable of 22
AWG conductors is used to connect the transmitter to the
controller unit. The transmitter box can be located on either
an inside wall or an outside wall, or even the ceiling if
necessary. If the transmitter is mounted outside, it must be in
a protected location so that wind and weather do not disturb
the transmitter air inlet. If the transmitter is mounted on the
inside of the building, the flexible vinyl tube that would be
connected to the exterior probe inlet must also be in a
protected location on the outside of the building.
To mount the transmitter box, remove the four screws that
join the top and bottom halves of the box, then use wood
screws through the holes in the base of the unit to mount the
box to an appropriate surface. Ensure that the wiring is
correct then fasten the top of the unit to the base with the four
screws previously removed from the housing. Make sure
that the tubing is not bent sharply which could interfere with
the pressure sensing function. Do not cut or pinch the tubing.

PARAMETERS
DESCRIPTION
The PEC-1 control unit should be installed where most
practical for operation. Electrical power corresponding to the
type of fan to be used is wired into the control. Verify that the
correct voltage is selected inside the control unit to match the
line voltage. Make sure that appropriate wiring codes are
used to determine wiring type and size. The output to the fan
is wired from the control unit so as to be able to control the
