Application guide
Condensation protection in old historic buildings
Danfoss Heating
Application
Humidity and room temperatures are critical
factors in old historic buildings like churches,
castles, manors, museums and wine cellars.
If the relative humidity gets too high it can be
damaging for artworks, murals, organs and
wine.
To avoid damages to inventory in old historic
buildings Danfoss Heating recommends a
control solution that in addition eliminates
problems with mould and ensures a
comfortable and preservative climate for both
organs, artworks and people.
We recommend
• A230 application key (use subtyp e A230.3)
• ECL Comfort 210, 296 or 310 controller
• ECA 31 remote control
• ECL Portal (only ECL 296 / 310)
• AME, AMV, AMB actuators
• ESM temperature sensors
ECL Comfort 310 controller with
application key
The A230 application key is a so -called fourin-one solution offering 1) temperature
control in heating installations, 2) temperature control in cooling installations 3) control
against too high humidity and 4) a floor
(screed) drying program - dependent on the
selected subtype of the key.
The ECL application key A230 contains
4 subtypes, applicable in ECL Comfort 210,
296 and 310:
• A230.1: Temperature control in heating
installations. Optional compensation
from wind.
• A230.2: Temperature control in
cooling installations. Optional external
signal (0 - 10 V) for temperature setpoint.
• A230.3: Condensation protection
(RH signal from ECA 31 or as 0-10 V signal).
• A230.4: Temperature control in heating
installations. Optional external signal
(0 - 10 V) for flow temperature setpoint
or pressure measuring.
Additional temperature monitoring
included.
• By using the ECA 32 or ECA 35
extension module to the ECL Comfort
310 controller, the actuator for the
control valve can be alternatively
controlled via a 0 – 10 V output.
• The A230 application key also contains
a floor (screed) dr ying program for the
subtypes A230.1, A230.3 and A230.4.
The elapse of the program can be saved
for later documentation, if necessary.
Up to two remote control units, ECA 30 / 31,
can be connected to one ECL controller to
control the ECL controller remotely.
The ECL Comfort 296 and 310 controllers can
be connected to the Internet-based ECL
Portal for remote monitoring and control.
In addition, a smartphone app is available
for the ECL Portal.
The ECL Portal is an effective tool for the
service personnel to streamline service,
commissioning, maintenance and control
tasks. Also, alarm messages can be sent
directly to users via e-mails.
The ECL Portal is an internet-based SCADA
solution that requires no local server. It
automatically configures its user interface
and functionalit y to support the application
in the controller.
All communication interfaces related to
the use of the ECL Portal and ECL Comfort
296 / 310 are encrypted (SSL/ TLS certificates
(https) on the ECL Portal web pages and AES
128-bit encryption in the communication
between the ECL Comfort 296 / 310 and ECL
Portal), preventing unauthorized persons
to tap into the data communication and
steal or manipulate settings and personal
data.

Indirectly connected heating system. Optional wind compensation and protection against condensation in thermal heavy buildings.
S2: ECA 31 contains room temperature sensor and humidity sensor and sends the RH signal to the ECL.
Additional accessories and options
AMV and AME actuators
AMV and AME actuators are primarily
designed to operate valves in the
respond to the demand of a controller in
e.g. district heating, district cooling and
HVAC systems.
They can be controlled by electronic
controllers with modulating (0 - 10 V) or
3-point control output.
Actuators have built-in thermic and
overload protection of the electro
motor. This radically reduces the risk of
operational failure in either the valve or
the system as a whole.
Feel free to contact us or visit www.heating.danfoss.com or https://store.danfoss.com for further information about Danfoss Heating products.
Other features:
• High-temperature resistance
• Easy mechanical and electrical
connection
• Robust design
AMV and AME actuators are mostly
used with VS, VM, VB and VFM valves
or with pressure independent valves
AVQM and AFQM.
