The enthalpic core installed in ERVs requires extra protection when the outside temperature drops below
-15°C (5°F).
A special operating mode called TBI (Time-Based Intermittent) is activated under these conditions.
Characteristics of cold weather TBI mode
• activated when the outside temperature drops below -15°C (5°F).
• 20/40 cycle (20 minutes LOW speed followed by 40 minutes OFF).
• usual control of air supply via the main wall control is suspended (except for the OFF position).
• optional control (20/40/60-minute push button) retain its temporary high speed activation capability.
• deactivated when the outside temperature warms up higher than -15°C (5°F).

F URNACE INTERLOCK (for forced air heating system)
The furnace fan can be interlocked so that it will run simultaneously with the ERV or HRV to ensure proper
distribution of fresh air throughout the house (see table section 7.4, to see if it is available on your unit).
P
ERMANENT MEMORY
Our electronic controls have a default memory feature in the event of a power outage. Even the date of the
last service reminder is maintained as a convenience to the homeowner.
C ONTROL UPGRADES
All controls can be used on any ERV, so a Basic control can be upgraded to the Electronic in the future
(see table in Section 7.4 below for control availability according to the units).
