Wiring diagram
LW 9 Air flow monitor
S1 Air flow monitor sensor before the
ERH..
JP1 Plug jumper on operating mode
"H". Relay switches on as the
temperature drops.
TH 10 Thermostat
R1 Temperature sensor after ERH 16-2
US 16 T Universal contactor
ERH 16-2 Electric air heater
(preheating register)
The air flow controller sensor "S1" must be
installed in the air flow direction, at least
30 cm ahead of the electrical air heater.
The TH 10 temperature sensor "R1" must be
installed in the air flow direction, at least
50 cm after the electrical air heater.
We recommend installing the filter box
TFE 25-4 (with G4 filter) to protect the
electrical air heater against dirt. If a filter box
is used, the G4 filter in the outside air channel
can be removed from the heat recovery unit.
An earth heat exchanger as an air or brine
collector can be used to keep the heat
exchanger free of frost.
Make sure there is protection against
i
condensation for the external heat
register, filter box, outside air and
outgoing air channel: These must be
diffusion-resistant insulated to protect
against condensation.
