Both S10 ERVplus, S10n ERVplus, 70E+ and 70E
S10 ERV ECM, S10c ERV, 70E, 70E ECM and 70Ec units can also be controlled using an optional main control.
NOTES: 1. The integrated control must be turned OFF on S10 ERV, S10 ERV ECM, S10c ERV, 70E, 70E ECM and 70Ec units 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.
Always disconnect the unit before making any connections. Failure in disconnecting power could result in electric
shock or damage of the wall control or electronic module inside the unit.
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.
Open the unit door. Insert the terminal connector (included in the
installation kit) under the unit, on the electrical compartment front face.
Use this terminal connector to perform the electrical connection for main
and optional wall controls, then secure the cable(s) with a tie wrap (see
illustration at right).
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).
