Defi nitions
Improper installation and operation of this control could result
in damage to the equipment and possibly even personal
injury or death. It is your responsibility to ensure that this
control is safely installed according to all applicable codes
and standards. This electronic control is not intended for
uses as a primary limit control. Other controls that are
intended and certified as safety limits must be placed into
the control circuit. Do not attempt to service the control.
Refer to qualified personnel for servicing. There are no
user serviceable parts. Attempting to do so voids warranty
and could result in damage to the equipment and possibly
even personal injury or death.
Caution
Choose the placement of the setpoint control early in
the construction process to enable proper wiring during
rough-in.
Consider the following:
•
Interior Wall.
•
Keep dry. Avoid potential leakage onto the control.
RH 80% to 88°F (31°C), down to 50% from 104 to
122°F (40 to 50°C). Non-condensing environment.
•
No exposure to extreme temperatures beyond 32 - 122°F
(0 - 50°C).
•
No draft, direct sun, or other cause for inaccurate
temperature readings.
•
Away from equipment, appliances, or other sources of
electrical interference.
•
Easy access for wiring, viewing, and adjusting the
display screen.
•
Approximately 5 ft. (1.5 m) off the finished floor.
Use standard 18 AWG wire for the control power, relays,
tN4 and sensor connections.
Refer to the diagram below to determine the number of
