A pinging noise caused by water being picked up and thrown against
the condenser on rainy days or when the humidity is high may be
heard. This design feature helps remove moisture and improve
e󰀩ciency.
Relays click when the controls cycle on and o󰀨 or are adjusted to
change the room temperature may be heard.
Water will collect in the base pan during high humidity or on rainy
days. The water may overow and drip from the outdoor side of the
unit.
The indoor fan runs continuously when the unit is operating in the
cooling mode, unless the Smart Fan Auxiliary Control is set to cycle.
This will cause the fan to cycle on and o󰀨 with the compressor. A fan
noise stop and start may also be heard.
There are times when the fan on the unit will run even when the unit
is not heating or cooling. If the system is set up to be in continuous
fan the indoor fan will run regardless if the unit may be cooling or
heating. Other times the fan will run longer than the heating/cooling
cycle or kick on occasionally. This is normal and is done to improve
room comfort and balance.
If the unit is equipped with a make-up air ventilation system, fans will
run continuously.
Digital makeup air unit will perform a system check upon power up,
power cycle, and once every 7 days if the unit is in occupancy mode.
The system check lasts approximately 45-seconds. During this time
the fans will speed up, slow down and then go to the set point.
A user may notice a few minutes delay in starting if they try to
restart the Zoneline too soon after turning it o󰀨 or if the thermostat
is adjusted right after the compressor has shut o󰀨. This is due to a
built-in restart protector for the compressor that causes a 3-minute
delay.
During the defrost cycle, both indoor and outdoor fans stop, and the
compressor will operate in the cooling mode to remove frost from
the outdoor coil. After defrost, the unit will restart in electric heat to
quickly warm the room to the desired comfort level.
To protect the compressor and prevent short cycling, the unit is
designed to run for a minimum of 3-minutes after the compressor
starts at any thermostat setting.
