The ERV100SP unit must be controlled by a main control. For more convenience, the ERV100S unit can also be controlled using
an optional main control.
NOTES: 1. The integrated control must be turned OFF on ERV100S unit to use an optional main control.
2. If an optional auxiliary control is used, if activated, this auxiliary control will override the optional main control operation.
CAUTION
Never install more than one main wall control per unit. Make sure that the wires do not short-circuit between
themselves or by touching any other components on the wall control. Avoid poor wiring connections. To reduce
electrical interference (noise) potential, do not run wall control wiring next to control contactors or near light dimming
circuits, electrical motors, dwelling/building power or lighting wiring, or power distribution panel.
Check if all wires are correctly inserted in their corresponding holes in the terminal
block. (A wire is correctly inserted when its orange receptacle is lower than another
one without wire. On illustration at right, wire
A
is correctly inserted, but not wire
B
.)
Splice back the end of the cable to access the 4 wires. Strip the end of each wire.
Connect each wire to its corresponding terminal: YELLOW wire to “Y’’, RED wire to “R’’,
GREEN wire to “G’’ and BLACK wire to “B’’.
Connect the auxiliary control cable, if installed (not shown).
