See “Lumina Wall Control and Installation Guide” for details.
6.1.1
ES Control Wiring – applicable to all ES series controls
Crossing the +12V/12 and ground (G)
wires might short-circuit and destroy
the ES wall control processor.
Note:
If you are using
ONLY
an
ES-T1
to
control your unit, you must connect a jumper
wire between R and SB on the 24V (10-wire)
removable terminal block. In this situation
you can add continuous low speed operation by
connecting a jumper wire between R and LO.
Consult local building code in case a centrally located control with an on/off switch is required.
6.2
Winsor Series & Other 24 VAC Control Options
Windsor Series and other 24VAC controls (sold separately) connect to the 24V (10-wire)
removable terminal block.
6.2.1
Terminal Designation/Function
Normally closed – a dry relay contact paired with I that opens when the HRV is running
I – interlock – a common relay terminal used with NC or NO. See Sec. 8
Normally open - a dry relay contact paired with I that closes when the HRV is running
24 VAC output
24 VAC common return
Timer Light – used only with WIN-20
Timer Switch – used only with WIN-20
Stand By – a closed switch across SB- R makes HRV dampers active, fans are off.
High – a closed switch across Hi-R makes HRV run in high speed
Low – a closed switch across Lo-R makes HRV run in low speed.
6.2.2
Building Automation and Control Systems
The HRV does not communicate with BMS. Dry relay contacts from the BMS can used to enable 3
modes of operation. R-SB, R-Lo, R-Hi. If 2 or mores are called simultaneously, the highest fan speed
results.
