NOTE
:
This control is designed to be used primarily with
installations which are independent of a forced air system.
1. Initially the switch is off. All LEDs are off and HRV is in-
operative
2. First push of mode button puts HRV into intermittent mode.
The HRV operates at high speed when there is a call for de-
humidification. Intermittent and exchange LEDs are illu-
minated. When dehumidistat is satisfied, HRV shuts down
and exchange LED goes out.
3. Next push of mode button puts system in continuous mode.
Continuous and exchange LEDs remain on. The HRV oper-
ates at high--speed blower during calls for dehumidification
and low--speed when dehumidistat is satisfied.
4. Next push of mode button and exchange puts system in cir-
culation mode. HRV operates in high speed at all times. Cir-
culation LED remains on. When there is a call for dehumid-
ification, exchange LED is on and HRV exchanges air with
outside. When dehumidistat is satisfied, HRV dampers close
which recirculates indoor air. The exchange LED goes off.
5. The maintenance light illuminates every 3 months to indic-
ate filter should be cleaned. It is reset by opening the door to
the HRV.
NOTE
: The standard and automatic controls sense humidity not
temperature. Either control must be located in an area where it will
continually monitor fresh air circulating within the home. Install
HRV wall control as close as possible to main system thermostat
and follow same guidelines as installing a thermostat, (locate
approximately 5 ft. (1.5 m) above floor, mount on an inside
partitioning wall, etc.).
NOTE
: The HRV may be controlled using the Infinity System
Control. The HRV may be connected using either a NIM or a
4--Zone Damper Module. See the appropriate instructions if using
the NIM of a 4--Zone Damper Module for connection instructions.
Blower interlock relay is not needed for use with the Infinity
system control. The Infinity System Control will simultaneously
control the HRV and the indoor blower.
Push Button Timers may be used and are connected to the HRV as
shown in Fig. 6. However, the Infinity system should be set to
continuous fan to ensure that the fresh air is circulated in the home.
In a Zoned System, at least one zone should be set to continuous
fan.

OPERATING THE HRV WITH THE
INFINITY AND EVOLUTION CONTROL
The ventilator has four settings in heating mode and three settings
in cooling mode.
Heating:
AUTO -- the ventilator selects the speed based on indoor humidity
and outdoor temperature. It may cycle on/off every 30 minutes
depending on humidity and outside temperature.
LOW -- low speed all of the time.
HIGH -- high speed all of the time.
DEHUM -- will only turn on if humidity is 3% over setpoint. The
speed is determined by indoor humidity and outdoor temperature.
