This version of the Mitsubishi Electric Pre-Plumbed Slimline Cylinder is the fourth generation in terms of its control
systems and the design of key mechanical components.
As you would expect there have been many technological changes based around our experience of producing
premium quality cylinders optimised to work with our Ecodan
For those familiar with previous generations of our cylinders the most obvious change is the addition of a larger,
FTC4 control centre providing greater flexibility and additional functionality when compared with the outgoing FTC2
versions. Some Key FTC4 features are shown below.
Weather Compensation
2 Heating Zones
Backup Heater Control Option
Adaptive Room Compensation
Built in Immersion Control
SD Card Commissioning
Intelligent Fossil Fuel Boiler Control
Multiple Unit Control
Wi-Fi Ready
High Limit Control
The main controller replaces the room thermostat, time clock and commissioning controller previously supplied.
In 'Room Compensation' mode this controller measures and records actual and target room temperature which
when combined with other sensor readings allow the system to calculate the minimum required flow temperature,
meaning the Ecodan
is intended to be used as the main thermostat. It should not be installed within the cylinder cupboard.
FTC4 based systems also have the ability to control multiple Ecodan
a single system. Further details of how to achieve these types of setup can be found later in this manual.
Precise control of any immersion heater fitted is now available directly from FTC4 so there is no need to add any
third party relays as was the case with FTC2 systems. Immersion heater strategy can be edited in terms of
maximum temperature, frequency, start time and duration of maximum temperature to ensure that the
pasteurisation cycle consumes the minimum amount of electricity and can be tailored for any installation.
The TH5 sensor acts as the control thermostat, there is a separate mechanical high limit thermostat fitted which
in the event of failure will cut the power supply to the FTC4 and hence all spring return valves will close providing
mechanical isolation.
Other features such as SD card input and the potential for Wi-Fi connectivity will mean that commissioning and
fault finding on FTC4 based systems will become quicker and easier.
