OPTIONaL SUMMER CORE DEFROST SCHEDULE
When using the summer core, the Summer/Winter switch at the left hand side of
the HRV must be set to summer. When the summer switch is ON the following
defrost schedule is followed for temperatures below -5.5°C (22°F) and below
-15°C (5°F) .
While the temperature is above -5.5°C (22°F) the system operates normally.
While the temperature is below -5.5°C (22°F) and above -15°C (5°F) , the
system will run a defrost cycle (fan high) for 6 minutes. At the end of the defrost
period the system will return to the previously selected mode. After 32 minutes,
if the temperature is below -5.5°C (22°F) but above -15°C (5°F), this defrost
cycle will be repeated.
If the temperature is below -15°C (5°F) , the system will run the 6 minutes
defrost period and then switch to fans off. After 54 minutes, if the temperature is
below -15°C (5°F) , the 6 minute/54 minute schedule will be repeated. If the
temperature remains below -15°C (5°F) for four cycles of 6-54 the system go
to the System Off mode. The system Off LEDs will blink and the will display
INSTALL WINTER CORE. If the temperature remains above -15°C (5°F) for
more than an hour, the cycle count will be reset to zero. This permits the system
to continue to operate if the temperature is only below -15°C (5°F) for less than
four hours.
NOTE THAT THE SUMMER CORE WILL BE PERMANENTLY DAMAGED
SHOULD IT BE EXPOSED TO TEMPERATURES BELOW ---- 15°C (5°F) .
When the summer core is installed in the HRV the select switch on the left
hand side must be set to summer.
Failure to do so will result in permanent
core damage.
When using the winter core, this select switch must be set to winter to ensure
proper HRV operation during the colder periods.
