Interlocking the HRV/ERV to an Air Handler/Furnace Blower

Connecting the HRV/ERV as illustrated will ensure the Air

Handler/Furnace Blower Motor is operating whenever the

HRV/ERV is ventilating.
The HRV/ERV must be interlocked to the Furnace/Air

Handler with a Simplified Installation (Return/Return

Installation) and should be interlocked with a Partially

Dedicated Installation.

Operating the HRV/ERV without a Main Control and Adding Dry Contact Controls

CAUTION

Consideration should be given to competing
airflows when connecting the HRV/ERV in
conjunction with an Air Handler/Furnace Blower
system.

Setting “Standby” when using a Main Control

CAUTION

Building codes in some areas require “fully-
off” functionality. Check with your local
building authority before modifying the unit
to “standby -off”.
Unintentional operation of the HRV by the
end user may occur if the unit is modified
from “fully-off” to “standby-off”.

The HRV/ERV will be “fully-off” when the

OFF position is selected on the Main Control.

Timers and /or other controls will not function

when the HRV/ERV is in the OFF position.

The “fully-off” feature can be modified to

“standby-off” by adding a jumper on the

Terminal Block between 2 (ON) and 3 (RED).

“Standby” can also be achieved by setting the

main control to the ON position and selecting

speed 0*. Timers and /or additional controls

will initiate high speed ventilation when

activated

.

* Speed 0 is not available on all controls

The Terminal Block

(located on the HRV/ERV)

A jumper must be in place between 2 (ON) and

3 (RED) on the Terminal Block to activate the

HRV/ERV for timers and/or dry contact

controls.

Adding Dry Contact Controls

Low Speed

- A jumper between 2 (ON) and

1 (LOW) initiates low speed ventilation.

High Speed

- A jumper between 2 (ON) and

6 (HI) initiates high speed ventilation.

Dehumidistat

- A dry contact for a dehumidistat

is connected between 2 (ON) and 10 (BLK).

The Terminal Block

(located on the HRV/ERV)

The HRV/ERV must have a Jumper in

place between 2 (ON) and 3 (RED) on

the Terminal Block when installing the

unit without a Main Control.
