The controller is provided with a programmable display that allows you to view and
set the hydronic unit functions by means of the specific interface with parameter
description.
SW - Water temperature sensor for microprocessor controls
model MYCOMFORT
Directly connected to the microprocessor control model MYCOMFORT
to measure the water temperature through the heat exchanger.
If the temperature detected is less than 17°C, the unit will operate in the
cooling mode and the controller will use the summertime temperature
scale (19 - 31°C); if the temperature detected is greater than 37°C the
unit will function in the heating mode and the controller will use the
wintertime temperature scale (14 / 26°C). If the temperature detected by the probe
is in the range of 17°C to 37°C, the controller will inhibit operation of the fan coil unit.
KP - Power interface for connecting in parallel up to 4 fan coil
units to one control
The KP interface is used to control up to 4 units (connected in
parallel) by means of a single control panel.
Suitable for mounting on DIN guides, usually installed in electric
control panels, it can be used with all IWC versions .
LED503
Recess wall-mounted microprocessor control
The proposed microprocessor control panels for Galletti indoor
units is completed by the LED503 command with LED display
that is designed for recess wall mounting.
CONTROLLER
The control software developed by the Galletti Software Dept.,
features:
- manual selection of fan speed;
- automatic selection of fan speed according to the difference between the set
temperature and the room air temperature;
- manual selection of heating/cooling operating mode;
- automatic selection of heating/cooling operating mode;
- control of 1 or 2 ON/OFF valves;
- control of additional heating element;
- on board timer function to detect the actual ambient temperature;
- reading of air ambient temperature, set point, fan speed and mode selection on the
LED display.
TD4T
Wall-mounted thermostat switch and summer/winter
selecting switch for 2 or 4-pipe systems with valves
Control panel for wall mounting, complete with speed switch,
electromechanical thermostat and summer-winter selector. It
governs the adjustment valves, if present. Fan speed control
and room temperature control:
- manual operating speed switching;
- room temperature control in both the heating and cooling
modes for 2 and 4 pipe systems, achieved by switching the fan off and on, at the
manually set speed and opening and closing the regulation valves.
