continuous pump op.: Select for continuous operation
of the circulation pump in the exhaust air module.
pump speed: Set the desired speed for the circulation
pump in the exhaust air module.
time between defrosts: Here, you can set the minimum
time that must pass between defrosts of the heat ex-
changer in the exhaust air module.
When the exhaust air module is in operation the heat
exchanger is cooled so that ice builds up on it. When
too much ice builds up the heat transfer capacity of the
heat exchanger is reduced and defrosting is required.
Defrosting warms up the heat exchanger so that the ice
melts and runs off via the condensation hose.
months btwn filter alarms: Here, you can set how many
months should pass before the heat pump notifies that
it is time to clean the filter in the exhaust air module.
Clean the exhaust air module's air filter regularly, how
often depends on the amount of dust in the ventilation
air.
activate cooling: Here, you can activate cooling via the
exhaust air module. When the function has been activ-
ated, the cooling settings are displayed in the menu
system.
Caution
The following menus require the accessory
HTS 40 and that "demand-contr. ventil." is activ-
ated in menu 4.1.11.
max. fan speed: Here, you set the highest permitted
fan speed during demand-controlled ventilation.
min. fan speed: Here, you set the lowest permitted fan
speed during demand-controlled ventilation.
contr. sensor 1 – 2: Here, you select which exhaust air
module(s) will be affected by which HTS unit(s). If two
or more HTS units control an exhaust air module, the
ventilation is adjusted according the units’ average value.
time between speed changes: Here, you set the time
it takes for the exhaust air module to increase/decrease
the fan speed step-by-step until the desired relative hu-
midity is obtained. At the factory setting, the fan speed
is adjusted by one percentage point every ten minutes.
TIP
See the accessory installation instructions for
function description.
