HMI EC (1-4-2801-0155)

MANUAL (2-1-0101-0047 ver. 06.2020)

HMI EC is a control panel, dedicated for all types of AIRSTREAM curtains. It has an interface with RTU Modbus protocol for easy integration with building management systems (BMS). It is characterised by very easy and intuitive operation due to the comfortable, practical keypad and backlit screen.
HMI EC controller has been made from electronic materials of the highest class. The panel is adapted for continuous operation with 230 V AC single- phase power supply. Due to the well-thought design, the controller is installed in a very easy manner on a special mounting bracket in the Ø60 mm flush mounting box. The mounting bracket enables easy installation and removal of the panel. Electric wires are connected directly to the terminal block, located at the back of the controller. The panel enables three-position regulation of rotational speed of the fans with EC motors, as well as three- position regulation of the heating power.
Due to the integrated thermostat and as well as programmer function, the controller enables to define operating parameters in the weekly schedule (on working days/at weekend, with 4 heating periods per 24 hours).

The installation of an external door sensor enables the selection of one of three modes of automatic operation:

• Door (default one): heating with the air supply or only the air supply, maintenance of set temperature. Active only with open door.
• Room: heating with the air supply or only the air supply (air supply activated manually), maintenance of the set temperature. Active regardless of the status of the door sensor.
• Door + room: heating with the air supply or only the air supply, maintenance of the set temperature. Active, depending on the status of the door sensor.
• HMI EC controller optimises the operation of the curtains, ensuring their continuous and reliable operation, and well-thought functions of the device enable significant power efficiency.

PRODUCT OVERVIEW

Explanation of the operating modes:

• Speed I: Programmable value in the range of 15-80%.
• Speed II: Programmable value in the range of 15-90%.
• Speed III: Programmable value in the range of 15-100%. Press to change the fan speed.
• The values of the individual gears can be set from the advanced settings A: function A5, A6 and A7.

AntiFrost : Frost protection of the heater medium. If the temperature falls below the set point, two-way valve opens. The function works even with deactivated controller or out of the working time set according to the calendar provided that controller is connected to a 230VAC power supply.

Programming mode
You may enter the advance settings A by holding the buttons [ ] for 5 seconds with the deactivated controller. You may go to the next set point by pressing the [Set] key. The values can be changed using [^] and [v] buttons. You may leave the programming mode by pressing any other button.

Calendar programming

When the controller is switched on, pressing the [Set] button for a longer time (approx. 5 seconds) will activate the function of weekly programming. You may go to the next set point by pressing the key. The value of specific set points is made using [Set], buttons. The calendar is programmed for each day of the week individually. In both cases, there is a possibility of programming a maximum of four heating periods during 24 hours. The programming takes place in the time scope referring to the time when a given function is to be activated. Leaving the calendar programming mode is possible by pressing power button.

Function ‘Door Optimum”

The AA function in the advanced settings A allows to program the “Door optimum” function.

• ‘’+0” – no increase of fan speed after door opening detection
• ‘’+1” – increase by +1 of fan speed after door opening detection
• ‘’+2” – increase by +2 of fan speed after door opening detection Function “Door Optimum” dependent on others founctions that were set up:
• When device is working in room mode function ‘’Door Optimum” doesn’t have influence on parameters of air curtains because only temperature parameter is relavent.
• When device is working in door mode or door + room mode function ‘’Door Optimum” influence on parameters of air curtains. Door opening detection is followed by increasing fan speed by the value that was set up in ‘’Door Optimum”. Door closing detection is followed by reducing fan speed by the value that was set up in ‘’Door Optimum”.

Extra heating time
The B1 function in the advanced settings A enables the user to program the function of heating the room after the door is closed. The time can be set between 0 and 90 seconds.
