E-1: TERMINAL LABEL
A low voltage remote control wiring interface is provided on the unit.
The connections for the low voltage remote wiring are located on
two terminals adjacent to the exhaust fan outlet (or adjacent to the
supply fan outlet on the 7000 unit). All field installed wiring must be
low voltage class II.

E-2: WALL CONTROL CONNECTION
Two types of remote wall controls are available:
1. Slide Switch Wall Control with fan switch and dehumidistat
control (for 6LC and 12LC units)
2. Pool Plus Wall Control with fan mode selection, dehumidistat
control and high speed recirculation mode (for 7000 unit).
The remote wall controls work with the microprocessor electronic
control within the unit to control ventilation sequences. Each wall
control has different features and require 4-wire connection to the
unit as shown below.
Without the wall control, fans can be operated with a remote fan
switch as shown in Appendix E-4.
NOTE:
When using a wall control, never use the the LOW, COMMON and
HIGH terminals.
