Technical description of the remote control DEI 758

Control system for a group of fan air-handling compartments (fan coil units, small air-handling units), united in a group control scheme with the possibility of dispatching.

Remote control DEI 758 LC

Individual control panel for the fan air-handling compartment (fan coil, small air-handling unit), working in conjunction with the power control unit DEI 758PN.

Remote control DEI 758 LCN

Group control panel for fan air-handling compartments (fan coil units, small air-handling units) with individual control packages: DEI 758LC + DEI 758PN. The maximum number of sets DEI 758 LC - PN, under the control of DEI 758 LCN - 63.

Application area

The proposed control system allows for the coordinated control of a group of fan air-handling compartments (fan coil units, small air-handling units) with the number up to 63 units. С единого диспетчерского (управляющего узла DEI 758 LCN). At the same time, each device is individually controlled by DEI 758LC + DEI 758PN set directly in the treated rooms.. The control package DEI 758 LC + DEI 758 PN allows to control the air handling fan compartment (fan coil, small air handling unit) with the first heating section and the first cooling section (four-pipe coolant supply system).

Functions

 DEI 758LC + DEI 758PN

• - Switching on (switching off) the air handling compartment directly from the control panel, through the power control unit installed on the compartmentDEI 758 PN;

• - Maintaining room air temperature in heating or cooling mode using the built-in temperature sensor.

• - Control of two-, three-way valves on the supply lines of the coolant of the four-pipe system).

• - Manual and automatic control of the fan speed of the air-handling compartment (high speed, medium, low, automatic).

• - The function of automatic switching on and off of the air-handling compartment according to the time schedule.

• - Non-volatile memory (saving the values of modes and settings installed before power is cut off).

• - Active illumination of the display screen for operating modes.
