External Controls - Thermoscreens T Series Operation And Maintenance

11. EXTERNAL CONTROLS

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 14). 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:

NOTE: Wire volt-free, remote switch contacts to 2-way screw terminals IN0 and IN1 using 2-core
cable.
WARNING: Do not apply any voltage to terminals IN0 and IN1 as this will damage the Ecopower
PCB inside the air curtain.
*
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.
