11.1 Remote switch contacts IN0, IN1
Terminals IN0 and IN1 on the Ecopower PCB inside the air
curtain can be used to provide different control strategies
using remote volt-free contacts (see Fig 9). This could be to
provide remote On/Off from a timer or BMS Digital/Output
contact, to work with a door switch or for simple weather
compensation control to disable heating when outdoor air
temperatures become warmer. Table 4 describes the
different functions:

Use the Remote Control to set up unit and
then hide it away if required. *
On/Off is then done via IN0 using a remote
volt-free contact.

WARNING:
Do not apply any voltage to terminals IN0 and IN1 as this will damage the Ecopower
PCB inside the air curtain.
NOTE:
Wire volt-free, remote switch contacts to 2-way screw terminals IN0 and IN1 using 2-core
cable.
*
NOTE:
The Ecopower Remote Control must stay plugged-in for the air curtain to keep working.
An optional plug-in EEPROM is available from Thermoscreens so the Remote Control can be un-
plugged and the air curtain stay working. Visit the Thermoscreens website for details.
