Operation

Self Test

The ventilator will automatically initiate a self test sequence when power is applied. Fan motor is cycled and then damper motor is cycled. Duration: Approximately 1.5 mins.

How much ventilation do I need?

During seasons when your windows and doors are closed (winter and summer if air conditioned) the HRV should operate continuously when the dwelling is occupied, and either continuously or intermittently when not occupied.

For most installations the HRV will normally be set to oper- ate continuously on low speed. To suit various lifestyles, the HRV offers a selection of operating modes.

Method of Operation

Good - intermittent operation at all times

Better - continuous operation during day or occupied conditions, intermittent at night or unoccupied

Best - recommended continuous operation of both HRV and furnace/air handler blower

Mode DIP Switch Settings

Figure 1 - Factory DIP Switch Settings

The factory setting of the DIP switches (located on the cir- cuit board) provides continuous low speed ventilation. Optional Remote Controls will initiate high speed ventila- tion.

Remote controls with an ON/OFF switch (refer to "Remote Control Devices" in this manual) will shut the entire sys- tem down when the remote control is in the OFF position. Changing the remote control from OFF to STANDBY can be achieved by Setting the DIP Switch as per Figure 2.

This DIP Switch Setting can be adjusted when using a system control that has an ON/OFF switch (refer to "Remote Control Devices" in this manual). "STANDBY" is achieved when the Remote Control Switch is in the "OFF" position. The Dehumidistat and Timers will initiate high speed ventilation regardless of the "ON/OFF" switch posi- tion when this DIP switch configuration is used.

Increasing Low Speed to Medium Low

The ventilator automatically operates on its lowest speed when plugged in or switched on. This setting is factory supplied from an autotransformer with two selectable low speeds. To switch to a continuous medium low speed, an installing contractor must interchange the red and blue wires from the autotransformer inside the electrical box. Whether or not this change is made, the HRV will only be able to access a single selected low speed.

High speed is available with the use of optional remote controls connected to the appropriate terminals inside the electrical box.
