Residential HRV/ERV

Getting Started
Before installing your ventilator, the unit must be congured to operate in SLAVE mode (see
page 20).
Depending on selection, the ZRTs will be designed to operate on 120V power or 24V power
provided by the ventilator itself. If you are not certain what you have, this can be easily
determined by the color of the wires on the ZRTs. All ZRTs will have one green (ground) and
two red (end switch) wires. The other two wires are black (120V) or yellow (24V).
ZRTs operating on 120V will require installation by a certied electrician. Low-voltage, 24V
units can be installed by anyone with basic wiring knowledge. If you are not comfortable
with this, please contact a local contractor for installation assistance.
Installing the Ventilator
For installation details on your HRV/ERV, please refer to page 17 Section “Mounting the Unit.”
Installing the Zone Register Terminal to the Ventilator
VentZone® kits provided with 24V ZRTs are designed to be powered completely through the
ventilator. Use of the 20/40/60 Minute Timer (P/N 611228) is recommended to prevent over
ventilation and/or frost damage to the heat exchanger in cold climates.
The basic VentZone® System is designed to provide a low volume continuous rate of
ventilation, with intermittent boost through the selected ZRT.
To enable the low speed mode, place a jumper between connections 1 and 3 on the
terminal block as shown below.
Note: A switch can be placed on this to activate and deactivate ventilation without interfering
with ZRT operation. This can be ideal for times of the year when opening a window is preferred
or the home is empty for extended periods of time, i.e. disabling the ventilator for seasonal
homes to lower electric costs when unoccupied.
Each ZRT will require its own timer. Connect as illustrated below.
