Technical Description of IR 12 Heating Controller
IR 12 Heating Controller (ver. IR12_KRB) is a heating system controller. The controller can
handle up to 2 heating zones (one with a mixing valve, one unmixed with a return mixing
valve OR two mixed zones with no return mixing valve), DHW heating, DHW and space
heating by a fireplace, and a solar thermal system with 1-3 solar storage tanks. The
controller can be upgraded with an OpenTherm communication module and module for third
solar storage tank, universal output and two universal inputs for temperature sensors.
IR 12 Heating Controller is controlled by 6 keys. Information is shown on a 4-line display. The
Controller features 13 inputs for temperatures measured (by Pt 1000 temperature sensors)
and one input for Ripple control signal. Further it features 10 relay outputs (250V 3A) and two
triac outputs (250V 1A).
The Controller is f itted with an Ethernet interface enabling connection to a tablet, PC or from
a mobile phone. Servicing, firmware upgrade or elementary visualization of the concerned
heating system can be performed via this interface. The Controller also features an RS 232
communication interface. A gas boiler can be controlled from an OT (OpenTherm) module.
1. How to operate IR 12 Controller
The controller is operated using 6 keys , , , , C, OK on its front panel.
The DISP key switches between User and Service display.
Note: The Service display is intended to show info on the Controller itself and therefore it is
not needed during common operation.

2.1 Heating zones
In this Menu, a user can adjust these parameters:
zone on switching on the zone on t he User level. When a zone gets switched off on
this level, also the circ ulation pump and valve outlets switch off as well. The
pump and valve outlets c an be activate d by frost pr otection funct ion if it is on.
In this controller vers ion, switching off zone 1 will switch off zone 2 as well!

Time programs can be set either for separate days, or in blocks Mo-Fr and Sa-Su.
When the program is being set for separate days, there are 2 transitions from Comfort to
Setback and 2 from Setback to Comfort for each day.
When the program is being set in blocks, there are similarly 2 transitions from Comfort to
Setback and 2 from Setback to Comfort for the blocks Mo-Fr and Sa-Su. An swering YES to
the question Copy program? will rewrite the respective time program blocks.
If program copying is not desired, let the question be with no and leave the menu by pressing

2.5 OTC curves
The controller works with a linear characteristics between separate points of the curve
showing how heating water temperature depends on the outdoor temperature. The real OTC
curve is entered into the controller using a 4-point polyline (see Fig.) with points E1; I1 to E4;
I4 (cf. the display picture).

OTC points settings:
Point I1 represents the highest temperature that can be calculated by the controller, while
point I4 represents the lowest temperature that can be calculated.
2.6 Operation data
All temperature inputs and logical output values of the controller are displayed here. The
logical value of 0 means a valve closed, pump not running; 1 means a valve open, pump
running. Temperatures shown in brackets mean desired values.

24
an extra option (fromZ1) and in suc h a case th e data fr om RC21 unit w ired to

no room sens.recalc. DTheat./room (°C) Temperature drop setting between heati ng water and
room temperature. E.g. the value 3 means that a desired change in room
temperature by 1°C needs a heating water te mperatur e change by some 3 °C.
This parameter is applied for operation without any room sensors.

control. It is not recommended to use values above 1.5. Such values can
cause valve cycling.

S 2.2 – Solar Zone Service Parameters Setting
Solar system may work with one, two or three hot water storage tanks. Their heating is
controlled by so call oscillating heating, i.e. the Controller tries to heat up Tank No. 1 first. If
this is not possible due to a low temperature difference between a solar collector and the
tank, and at the same time the difference for heating Tank 2 is sufficient, the Controller starts
heating Tank 2 for the preset time. After that time, the Controller interrupts heat ing Tank 2
and tests if a collector temperature grows. If not, heating Tank 2 continues. If the collector
temperature grows, the Controller waits until the temperature difference is fulfilled for Ta nk 1
and then its heating is started. Heating to Tank 3 is controlled in a similar way.
Solar (active/off) Switching on solar zone.
tank 1,2,3 (active/off) Switching on separate solar tanks.

max. temp. (°C) Max. temperature. Maximum temperature the solar tank is heated to under
normal mode (the function of solar collectors cooling is turned off).
Oscillating loading:
t.increase (°C) Temperature increase during oscillating loading. If a solar tank of a
higher priority cannot b e lo aded , t he Controller waits for the t ime s et in
parameter idle time. If the temperature rises after this time by the
value set in parameter t. increase, the Controller keeps idling. This
repeats until the tank sw itch-on differe nce is reac hed. If this condi tion
is not reached, the tank of lower priority is loaded, supposed the
28
condition of switching difference is met – cf. more details in the
description of Oscillating loading function.

temperature rises. The description see parameter t. increase.

loaded for the time period set in this parameter.
Collector cooling function:
When this function is on, solar collector is cooled. As soon as the max. temperature is
reached (in all tanks), tanks loading is stopped. When the solar collector temperature
exceeds the preset max. collector temperature, the circulation pump starts and the collector
is cooled by heating tank X. If the temperature in tank X exceeds the preset critical
temperature, collector cooling is stopped. Tank number (X) is set in parameter nmbr. of
solar tank for collect. cooling and tank cooling (see Solar tank cooling function).

run only until the tank temperatur e set by this param eter is reached. When this
temperature is exceeded in tank 1, the collector stops cooling.

If the temperature set in parameter crit.t. is exceeded in the collector, the solar pump is
blocked. This function protects other solar components from damage by too hot solar fluid.

solar tank No. 3 (option div.v.sol3), control a DHW recirculation pump (option circulat.),
control a heating zone 1 circulator (option zone 1 pump), or it may be used as a uni versal
thermostat (option thermostat).

can be used as a universal thermostat (option thermostat). Eventually the universal output
can be switched off completely.

or uni2 thermostat).

The universal thermostat features the following functions:
• thermostat 1
• thermostat 2
• differential thermostat
• delay
• overrun
• timer
The function logic is designed in such a way that the output is closed when the universal
thermostat is switched on and all the permitted functions are fulfilled, see fig. below. A
function not permitted is equivalent to a closed switch.
It is obvious from the picture that the Delay function can delay signal from thermostat and
diff. thermostat functions, the Overrun function can hold disconnection (switching off) from
thermostat, diff. thermostat and delay functions. The Timer function is superior over the
preceding functions.

overwritten. Always change the hydraulic variant first, before starting to
adjust other values.
Here the setting of the hydraulic variant is done, following the document: IR12 Intelligent
Controller - typical designs of hydraulic variants that is enclosed. T he document can be also
downloaded from the service level of the controller website.
After you select the Hydraulic variant number (press OK in the display shown, set the desired
number using up/down arrows in the range 1 to 34 and confirm by pressing OK), the control
type will be set automatically as well as all the other variables concerning the selected
variant.
For the control type 1, the heating return valve and temperature sensor are connected and
Zone 1 is unmixed. For the control type 2, Zone 1 is mixed (i.e. a zone mixing valve is
installed instead of a heating return valve) and a Zone 1 heating water temper ature sensor is
connected instead of a heating return temperature sensor. In that case the system features
no heating return valve.

The function logic is designed in such a way that the output is closed when the add-on
