PAR-31MAA Remote Controller
If the air curtain is to be manually controlled by the end user a
Mitsubishi Electric PAR-31MAA remote controller (not supplied by
Thermoscreens) must be supplied and fitted by the installer. This is
wired to terminals 1 and 2 on the air curtain using 2-core cable. Refer
to the Mitsubishi Electric instructions that come with the PAR-31MAA
remote controller for the installation and wiring of the controller.
A PAR-31MAA Remote Controller is also required for commissioning
purposes and if using AUTO mode with a BMS System or Centralised
Controller. Master/Slave control with a PAR-31MAA should be done
as follows:-
12V DC

NB. Y-Series systems need two controllers for AUTO control, Master controller at the lower
address, refer to Mitsubishi Electric for details.
A PAR-U02MEDA can also be used to manually control the air curtain. The PAR-
U02MEDA is a M-NET device and must be connected to terminals M1 & M2 on the air
curtain or anywhere in the M-NET wiring, it does not offer timed switching however.
Wiring of Air Curtain Fan Speed
As delivered the air curtain is set-up to provide 3-speed fan control (High, Medium and
Low) using a PAR-31MAA or PAR-U02MEDA remote controller. A suitable alternative is to
have a Door-Switch wired to switch the unit between a Higher fan speed - Door Open and
a Lower fan speed - Door Closed. This is both energy efficient and noise friendly. There is
a wire link that needs to be removed from the air curtain terminals and dip switch SW4
needs to be changed (the PAR-31MAA or PAR-U02MEDA remote controller will not then
provide 3-speed fan control). See Wiring Diagrams for details and Section,
Commissioning; 'Selecting the fan speeds of the air curtain' on page 25-26 which gives
details as to how the available speeds of the fan motor(s) can be set to suit outdoor
environmental conditions and indoor noise levels.
Condensate Disposal System
If it is intended to use the air curtain in cooling mode a condensate disposal system must
be installed.
The air curtain is fitted with a condensate drain tray with
15mm copper outlet pipe at the right hand side of the air
curtain. Suitable condensate hose can be fitted to the pipe
(see picture) and fed through a 20mm hole at the back of the
unit, see Figure 1, Page 11, so condensate will gravity drain
away. Means of condensate disposal must then be provided
at the rear of the air curtain.
