Cetetherm IQ Heat Midi/Maxi

Preconfigured DDC solution for Midi and Maxi. Ready to plug-in.

• Built in web pages for remote control. • Quick feedback during alarms and deviations.• No licens or extra programs needed.


Cetetherm IQ HeatWhy use IQ Heat?• Possible to directly solve heat problems before it starts to cost money.• Solve the heat problem from the office instead of using the service car.• Always available. Solve the problem from the office, hotell or airport.• Possible to directly see who is responsible for the heat problem and what

actions that are needed to solve the problem. The heat supplier, the heat customer or someone else?

• Easy to add modules/functions (energy saving, meter reading and data communication etc.) Only pay for what you are using.

• “Plug and Play” ready from factory, easy installation• During heat problems, Alfa Laval can do remote service through Internet.• Save time and get less phone calls from angry customers.


Cetetherm IQ HeatSiemens Saphir control platform

• Stable platform used for more than 10 years.

• Well known in cooling/heating applications.

• Module based platform. Easy to add extra I/O.

• Modules: TCP/IP, LonWorks, SMS-alarm, M-Bus, extra I/O, Web-server, OPC, BacNet.

• When there is a tight investment budget. Modules/functions can be added later on.

Cetetherm IQ HeatSteps performed in factory• Download software and services (web pages).

• Download control settings. Set geografical heat zone (for example, heat curve for north of Sweden).

• Functional test of communication modules.

• Functional test of sensors and motors.

Steps performed during installation (no programming needed)• Check all present values against setpoints.

• Acknowledge alarms.

• Check system clock.

• Connect TCP/IP cable and set ip address.


Cetetherm IQ HeatHot water regulation• 2 different set points normal (55 °C) and special (65°C).

• Quick stop if 70°C.

• Sensors on suppy and return pipes (hot water circulation).

• Customer selection: sensors are placed inside or outside the pipes.


Cetetherm IQ HeatHeat regulation, Heat circuit 1 and 2

• Heat curve with min, max and 5 set points.

• Parallell movement of heat curve.

• Timer function with 4 day schedule and 2 week schedule.

• Energy saving functionality.

• Indoor temperature sensors. Example, reduce heat supply when the indoor temperature is higher than 22 °C.

• Sensors on supply and return pipes / secondary and primary.


Cetetherm IQ HeatAlarm handler• Alarm list (15 items). Acknowledged alarms are moved to historical list.District Heating• Lower limit temperature, 60°C (10 minutes delay)Heat 1 / Heat 2• Deviation (when present value differ from set point) >5°C • Pump alarm• Alarm expansion tank ( open / closed ) Hot water• Deviation (when present value differ from set point) >5°C• Lower limit temperature 40°C• Higher limit temperature 70°C (Quick stop)Other• Detect mechanical error and short-circuits. Input/output for external alarms.
