PHRVR 305
Introducing the PHRVR 305 series of Heat Recovery
Ventilators (HRV) by Powrmatic. As with previous designs,
incoming fresh outdoor air is filtered before it is heated by
the stale outgoing air. The HRV then distributes the
preheated fresh filtered air throughout the home by direct
ductwork installed specifically for the HRV or through the
ductwork of a forced-air system.
NEW FEATURES:
• Balancing Dampers Included In Installation Kit
(not factory installed
)
• Electrostatic Filters (washable)
• External Screw Type Dry Contacts For Push Button
Timers (RTS 2), Dehumidistats 1, Dehumidistat 2
& 5MR Intellitek control
OPTIONAL CONTROLS
• 5MR – Digital Multi-Function Control
• DEH. 2 – Mechanical Low Voltage Dehumidistat with
On/Off Switch
• DEH. 1 – Mechanical Low Voltage Dehumidistat
• RTS 2 – 15 Minute Push Button Timer
• AQS 1 – Air Quality Sensor
External screw type dry contacts (provided)
SPECIFICATIONS

DEFROST A preset 5 minute defrost sequence is activated at
an outdoor air temperature of 23ÞF (-5ÞC) and lower.
During the PHRVR 305 defrost sequence, its mechanism
uses a motorized damper to temporarily block the incoming
fresh air stream allowing the warm air from the home to
circulate through the HRV. The exhaust blower shuts down &
the supply blower switches into high speed to maximize the
effectiveness of the defrost strategy.
The unit then returns to normal operation for 25 minutes,
and continues cycle.
SERVICEABILITY Core, filters, motors and drain pan can be
easily serviced through latched access door.
