Option 2:
Note:
Up to 4 Timer Switches (TC 100-5V)
and one intermittent switch (IC 100-5V)
can be connected to control board of
HRV/ERV by using three 24 AWG(min.)
standard Copper wires as shown.
Maximum total wire length 75ft.

But, overall functionality of both type of boards are same.
CONTROL BOARD: Old Version
Optional Accessories (Not Supplied)
a) Timer Switch (TC100)
b) Wall Switch
c) Dehumidistat
d) Time Delay Switch (TC100-120 & TC100-120P)
e) Master On/Off Switch
Recently we
modified
our control board layout to provide easy wiring connections for timer switches/ Intermittent switches (low
voltage) without accessing to our electrical box. Initially, some units may come with older version or newer version of control boards.
