1.2 How to use this manual
The TAC 2112 Manual describes all the functions and procedures
necessary to install, adjust and use the controller.
The TAC controller, as well as other products from the 2000-range,
should not be used for purposes other than intended for.
During normal operation
Before reading off or setting temperatures and other parameters
during normal operation, it is sufficient to read Chapter 3, “Using
the operator’s panel” and Chapter 4, “Day-to-day usage”. You can
also use the Quick Reference on the front of the controller.
During installation and commissioning
Before installing and commissioning the controller, you should read
Chapter 5, “Installation”. The enclosed document entitled
Installation instructions may also be used. A commissioning protocol
is supplied with the controller, but this can also be found in
Appendix A.
During troubleshooting
In the event of a fault with the controller you should read Chapter 3,
“Using the operator’s panel”, Chapter 4, “Day-to-day usage”, and
Chapter 6, “Troubleshooting”.
1.3 Associated documentation
Enclosed documentation

2 TAC 2112 Heating Controller
The TAC 2112 is a digital heating controller for controlling
waterborne heat in buildings.
The radiator circuit is controlled according to an outdoor temperature-
compensated reset curve, with or without a reference sensor.
The controller contains a real time clock and can be set for weekly
and yearly time schedules, along with powerful functions for optimum
energy saving.
It is very simple to read and set temperatures and other parameters.
The display window provides clear information with digits and
symbols.
The controller can be mounted on a norm rail, in a panel or on a wall.
TAC 2112, Manual TAC 2112 Heating Controller
2:2(2), 0-004-7459-3 (GB) 1999-08-01, TAC AB
The TAC 2112 is designed to control heat in apartment buildings,
offices, schools and other large buildings.
Installation with district heating
The controller operates both with and without reference sensors.
However, some optimisation functions require a reference sensor to
be installed.

3 Using the Operator’s Panel
3.1 Introduction
This chapter shows you how to use the buttons on the operator’s panel
and the display window to read off and set parameters such as
temperatures.
3.2 What is shown in the display window?
The display window provides you with information from the heating
installation in the form of digits and symbols.

3.2.1 Parameter numbers and parameter values
The controller has a list of 100 parameters numbered from 0 to 99.
Some of these parameters can be set (such as the setpoint for supply
temperature), while others can just be read (such as the outdoor
temperature). Some parameters cannot be displayed if the
corresponding function is blocked. For example, the room
temperature will not be displayed if there is no reference sensor.
The parameter numbers and parameter values in the display window
constitute a “window” to the list of parameters.
