The ES24V controls a ventilator to meet fresh air supply requirements
while limiting operation during periods of extreme temperature and/or
humidity.

MOUNTING
Front Cover Removal
Insert a flathead screwdriver into the slot
on the right side of the controller and
apply gentle pressure inward and up so
that the front cover disengages from the
back cover. Pull the front cover up and to
the left.
Back Cover Mounting
Locate the control on the mounting surface being sure to allow clearance
for the necessary wiring connections. Mark the mounting hole locations and
remove the back cover from the work space. Make the stripped/labelled
wiring connections now.
CAUTION: Be sure that no exposed portions of
wires are touching.
If installing onto wood, mount the back cover with the provided screws. If
installing onto drywall, drill pilot holes using a
7/32
”
drill bit (not
provided)
and tap the provided drywall anchors into place. Mount with provided
screws.
NOTE: Velcro can be used to mount the control instead of screws
if necessary.
Verify that wiring connections are correct and secure.
Align the front cover with the
back cover starting on the left
side. Push the front cover
towards the back cover in a
“hinging” motion from the left to
the right.
CAUTION: Make sure
the front cover is aligned properly
with the back cover to avoid
damaging the control.
Press
down until the front cover
snaps securely into place.
Sensor Mounting
The ES24V comes with a temperature sensor (26AWG, 2 wire) and
humidity sensor (6P6C, telephone wire), both 24
” long. Install the sensors
at a location so that they will be exposed to the fresh air intake (ex: the
fresh air ductwork). Drill 2, 3/4" diameter holes, spaced appropriately and
install the sensors with the provided hardware.
Use appropriate duct tape
to seal joints/openings as necessary.

OPERATING MODES
OFF Mode:
All outputs are off.
ON Mode:
Ventilation, Auxiliary 1 (if enabled), and Auxiliary 2 (if
enabled), Furnace Blower (if enabled) are on continuously.
Eco Mode:
limits ventilation during periods of extreme
temperature and/or humidity. Ventilation, Auxiliary 1 (when
enabled), and Auxiliary 2 (when enabled) will follow the user
settings when the outside air temperature/humidity is within the
user set limits (see Function Setting below). The ventilation
terminals will be activated for the user set amount of time per hour
while the temperature/humidity limits are within range. The
temperature/humidity sensors evaluate the fresh air conditions
every 10 seconds. While the fresh air temperature/humidity is
within the user set limits, ventilation, Auxiliary 1 (if enabled) &
Auxiliary 2 (if enabled) will turn on per the user settings. When the
fresh air temperature/humidity exceeds the user set limits, the
ventilation, Auxiliary 1 (if enabled) & Auxiliary 2 (if enabled)
terminals will turn off and engage a timer. The timer will activate
the ventilation terminals for 5 minutes every 15 minutes in order to
meet code requirements.
NOTE: the Furnace Blower (if enabled) will not run during this
check procedure to prevent cycling. The fan will continue this
check procedure until the temperature/humidity limits are within
the user set limits.
If Enabled (in SETUP):
The Furnace Blower will be on:
any time there is a call from “G”
Input or any time Ventilation is on (excluding the check procedure
above).
Auxiliary 1 will be on anytime the fresh air fan is on.
Auxiliary 2 will be on any time the fresh air fan is on.
(
Auxiliary 1, Furnace Blower and Auxiliary 2 are required to be
enabled in SETUP
)
