Thermoscreens / Mitsubishi Electric
Heat Pump Warm Air Curtain System
The Heat Pump Warm Air Curtain System consists of :-
•
a Thermoscreens 'PHV Air Curtain' fitted with a PAC-IF010 Mitsubishi Electric Interface
PCB
•
a Mitsubishi Electric 'Mr Slim Outdoor Unit'
•
a Thermoscreens 'Manual Room Control' for the manual control option by the occupant
Refer to Mitsubishi Electric if the air curtain is to be controlled via a Building Management
System (BMS) or Centralised Controller. Do not install Manual Room Control and
BMS/Centralised Control components together, install either one or the other.
A communications link is supplied to the Thermoscreens Heat Pump Air Curtain from the
Mitsubishi Electric Outdoor Unit. This link provides control of the heat output of the air curtain
and tells the air curtain when the outdoor unit is in defrost mode so auxiliary electric element
heaters (if specified) can provide partial heat back-up during the few minutes of defrost.
The Air Curtain requires a permanent 3 phase electrical supply (3L+N+E) from a local
switched spur to provide power to the defrost cycle electric heating elements, the air curtain
fans and the Mitsubishi Electric Interface PCB. If the defrost cycle electric elements are not
required they can be permanently disconnected, see 'Electrical Connections', and a 1 phase
electrical supply (1L+N+E) used instead.
High and Low Output in this document refers to the heat pump heating capacity of the Air
Curtain, not to any electrical rating.
