Mitsubishi air conditioner City Multi concealed duct unit PEFY-P250VMHS-E-F (fresh air)

The housing is made of galvanised steel with thermal insulation. Easy to install. All main components can be easily accessed for maintenance from below.

High-performance heat exchanger, as an evaporator / condenser, made of copper pipe with pressed-on aluminium fins with flared connections. The cooling system is dried, evacuated and filled with inert gas. Condensate tray insulated against condensation water

Directly driven fan, with an extremely quiet running, double-sided suction impeller with internal thermal protection, vibration-insulated mounting and dynamically balanced, 2 different settings.

• Microprocessor control for monitoring target temperature in cooling mode from 19 °C to 30 °C, in heating mode from 17 °C to 28 °C. Automatic switching between heating/cooling (R2 systems only or using optional TG2000 software with G50 central remote control).
• Special program for dehumidifying room air. All values entered are saved in the event of power failure.
• Automatic restart after power failure, temperature adjustment in heating mode, air outlet direction can be adjusted in cooling mode, lock or release the slats, autostart for indoor units when power supply active, external static pressure can be selected via DIP switch.
• Timer control. Fault diagnostics system with fault memory. In the event of a fault, the unit is immediately shut off and an error code is displayed on the remote control.
• The LEV valve is closed via the voltage bus to protect against ice formation.
• Faults in other devices in the system are shown on the remote control and indicate the device number (address).
• Monitoring and control of the integrated electronic injection valve (LEV) along the MSS curve in order to achieve optimum efficiency for the heat exchanger in all operating states.
• Three thermistors form a 3-point regulating circuit for precisely maintaining the set room temperature.
• Monitoring of evaporator surface temperature with protection against ice formation.
• Testing and emergency operation programs.
