Appendix F: Terminal Control Diagrams
Wall Control Connection
Three types of remote wall controls are available:
1. Standard wall control with fan switch and dehumidi-
stat control.
2. Xtra wall control with fan mode selection, dehumidi-
stat control and maintenance indicator.
3. Aqua Air wall control with fan mode selection, dehu-
midistat control and high speed recirculation mode.
The remote wall controls work with the integrated elec-
tronic controls within the unit to control ventilation
sequences. Each wall control has different features and
requires four-wire connection to the unit as shown below.
Without the wall control, fans can be operated with a re-
mote fan switch as shown in Remote Fan Control.
Occupied Timer/Sensor Connection
Occupancy control is achieved by connection to the termi-
nal interface shown below. These terminals require a dry
contact which could be provided by a number of types of
controls such as a timer, light sensor, occupancy sensor,
Building Management System or other. The unit will not
operate unless these contacts are closed!
The illustration below shows a factory installed jumper and
programmable timer option.
IMPORTANT
All controls accessories (ex. night setback timer, CO
2
con-
troller, enthalpy controller or smoke detector) intended
to provide a contact closure for occupancy control across
terminals 3 and 4 (left side) cannot be used in conjunc-
tion with the Xtra or Aqua Air wall controls.
If a wall control is required in addition to any of these
options, only the standard wall control may be used.
Without these options, a factory installed jumper across
terminals 3 and 4 (left side) must be installed.
