WhatistheTCB-IFCB5-PE?

This is an application control PC Board that is capable of providing two different control functions when connected to a Toshiba Indoor Unit, these are:

•Window Switch

•Remote On/Off Interface Controller

WhatisaWindowSwitch?

A Window Switch is a device used to ensure that an Indoor unit does not operate when a window in the air conditioned space is open.

Why use a Window Switch?

A window switch increases the efficiency and working life of the system by reducing the amount of energy that would be wasted in conditioning the outside air that flows into the conditioned space whilst the window is open.

Not only does this help to increase environmental friendliness of your Toshiba conditioned buildings but also helps to reduce the cost of running your Toshiba equipment.

How does the Window Switch Interface work?

The Toshiba window switch operates with the use of a locally procured window switch interface (Volt-Free Contact).

This switch is fitted to the window such that the contact is made when the window is closed, and broken when the window is open.

Each time the window is opened (contact open) the Indoor

Unit operation is turned Off and will not operate again until the window is closed.

There are two possible operation selections for when the window is closed again.

•StandardFunctionMode

The Indoor Unit operation remains Off.

•ReturnFunctionMode

The Indoor Unit will revert to the last setting before the window was opened.

This function also allows the Interface to remember any ON commands sent to the Indoor Unit from another controller whilst the window is open, then using this information, it will switchtheIndoorUnitONwhenthewindowisclosedregardless of the previous setting.
