7. Central control and monitoring
from heat production to heat use
Electronic control with ECL Comfort
Danfoss develops and produces most
of its flat station components itself. This
results in crucial benefits for electronic
control in particular. The controllers of the
new ECL Comfort series can consequently
perform the following controlling tasks:
• Requirement dependent control of a
district heat transfer station
• Buffer management acceptance
• Control and regulation of the system
pumps
• Weather compensated control of the
supply temperature
• Contact point for heat sources
Central control and monitoring
The use of central control and monitoring
system is recommended to optimise operation
and billing in heating system, from
energy production to decentralized heat
distribution and domestic water heating.
For this very purpose Danfoss flat stations
offer a complete solution ranging from
weather compensated heat production to
buffer tank management, through to the
control of each individual flat station.
The “master” in this system is the freely
programmable ECL Apex 20, which works
with the ECL Apex Web Panel or a PC as a
control unit that assumes the temperature
and pressure control, pump management
and system monitoring.
For integration into the system, every flat
station must be fitted with the networkenabled
ECL Comfort 310, which communicates
via Modbus with the Apex 20.
Consumer data for hot and cold water can
therefore also be transferred, centrally
recorded and billed.
The most important benefits of central
control and monitoring are:
• Weather compensated heat production
(boiler, local and district heating)
• Optimum buffer tank and solar management
• Highest possible system operation reliability
• Energy efficient energy distribution
• Central consumption recording and
billing
