9 ACCESSORIES
VK - ON-OFF 3-way motor driven valve, with
hydraulic kit
The ON/OFF motor driven VK 3-way valve /
4 connections kit connected to the control
panel for éstro fan coils, controls the room
temperature by stopping the water flow through
the heat exchanger. VK kit is available in various
configurations for all models of éstro fan coils
with standard (VK S) or additional DF (VK DF)
heat exchanger, as shown in the table below:
The kit includes:
brass 3-way valve / 4 connections with built-in by-pass, maximum operating
pressure 16 bar.
Electrothermal actuator with the ON/OFF functions (total opening time 4
minutes), 230 V power supply;
Hydraulic kit for installing the valve on the heat exchanger, complete with 2
holders for balancing and regulating the fan coil unit.
BV - Auxiliary water drip tray for vertical
installation units
The auxiliary drip tray is used to collect the
condensate from the valve and the pressure
regulator. It can be used on all éstro fan coils.
BH - Auxiliary water drip tray for horizontal
installation units
The BH auxiliary drip tray is suitable for
horizontal installation fan coils to collect the
condensate from the ON/OFF 3-way valve (VK
S accessory).
RE - Electric heating element complete with
installation kit, safety devices and power
relay box
Designed to meet the needs of supplement
conventional water heating systems,the kit
includes armoured electric heating elements,
safety thermostats (with automatic/manual
resetting) and power relay set.
The additional heating element should be coupled to the MYCOMFORT
LARGE control panel.
KSC - Condensate drainage pump kit
It permits the drainage of condensate in case
of height differences. The pump is equipped
with a check valve on the drain pipe and is
capable to drain up to 8 l/h of water.
RA / RM - Inlet and outlet connectors
These accessories are designed for éstro GT
GTFC, GTFF fan coils and are used for room
ducts when the basic unit (éstro GT GTFC) is
placed within false ceilings and/or recess wall
mounted. For each configuration, the inlet
and outlet connectors are available in straight
version and in 90° jointed version.
GIVK - Valve insulation shell
The GIVK valve insulation shell avoids the
creation of condensate within the valve body.
The plumbing connections are provided either
on the right side or the left side.
MCSWE - 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.
MCSUE - Humidity sensor for on-board
microprocessor controls model MYCOMFORT
LARGE.
