1. What is your new heating controller able to do?
Your heating controller makes sure, that your home will become even more comfortable. You can define your
individual comfort-temperature for any time. You can exactly control the room temperature and the tempera-
ture of your hot water, as you like it. That means: maximum comfort, maximum economy and maximum
environmental protection!
Regardless if you want to control one or two heating circuits or if you want to control the hot water support as
well: your heating specialist chooses the suitable configuration for you. In the commissioning manual he finds
all possible configurations to adjust your heating controller to your building situation in an optimal way.

1.1. Two types of the heating controller are available
LATHERM HZR COMFORT (HZR-C): 8 configurations and 6 relays – for maximum adjustment and regula-
tion comfort.
LATHERM HZR EXTENSION CON-
TROLLER (HZR-E):
Up to 7 extension controllers can be connected by eBus to your
heating controller. So you can control up to 8 heating circuits com-
fortably.
2. se as intended
The controller is intended for weather or room-controlled regulation of heaters including hot water support.
Another application is not permissible and is considered as inappropriate. The heating controller corresponds
to the state of the art and the appropriate safety regulations of the Guidelines on Electromagnetic Conformity
(2004/108/EG), the Low Voltage Directive (2006/95/EG) and the harmonized standards DIN EN 60730-1 and
DIN EN 60730-2-9.
The heating controller may only be installed and operated in:
 dry, not explosive surrounding areas
 closed rooms
 rooms with a temperature between 0 °C and + 50 °C
3. Safety advices
Danger to life due to electric shock!
Only trained, competent and authorised persons (electrical technician according to DIN VDE 1000-10
and BGV A3) are allowed to do mounting, electrical installation and commissioning, maintenance and
repair work on the heating controller!
DANGER
Attention!
 Never bring easily inflammable materials near to the controller!
 Protect the controller against humidity, coldness, heat, dust and strong sunlight!
 The controller may be damaged, even if it falls down of a low height!
 The controller is only allowed to be operated in perfect technical condition. Damages, that affect
safety or the proper functioning of the controller, have to be removed at once from competent and
authorised persons!
!
4. Warranty and liability
All regulations about warranty and liability are defined in the general terms and conditions of the manufacturer
or in the particular contractual relationship. arranty and liability claims are generally excluded in these cases:
 if damages result of inappropriate use of the heating controller
 if the housing had been opened unauthorised, unauthorised structural modifications or adjustments on the
controller software had been implemented
 if the electrical technician had executed mounting or repair work improperly
 if safety advices or instructions of the operating or the commissioning manual had been ignored
5. Location of the manuals
The operating and the commissioning manual have to be handed out to the technician before mounting work is
started. They have to be stored in readable condition near to the controller in order to ensure quick access if
needed.

12. Submenu information
This submenu shows the temperatures of the connected sensors. It depends on your heating system and its
configuration, which sensors are mounted at your heating system. For this reason it is possible, that your
controller does not display all values, that are shown in the following chart.
Coming from the starting display press the key two times, until ”i“ appears on the display. Acknowledge
with the key and you will get to the temperature display.
On the display Meaning
F1 TA Outside temperature
F2 TK Boiler temperature
F3 TV Flow temperature
F4 T ater temperature
F1-F5 TI, TR,
TF, KF
Depending on the configuration: room temperature (TI), return flow temperature
(TR), floor heating temperature (TF) or jumper for boiler value control (KF)
F8 TI, KF Room temperature, that is measured by an analog remote control (TI) or jumper for
boiler value control (KF)
The symbol (serial interface active) appears in the display in addition to the shown value, that is
transferred by another bus sharing unit. The values of the sensors are not shown in the display anymore.

The following standard switching times are preset for the desired day temperatures:
Day Standard switching time for day
temperatures
Standard switching times for
night temperatures or OFF
Monday – Thursday 6:00 to 22:00 o´clock 22:00 to 6:00 o´clock
Friday 6:00 to 23:00 o´clock 23:00 to 7:00 o´clock
Saturday 7:00 to 23:00 o´clock 23:00 to 7:00 o´clock
Sunday 7:00 to 22:00 o´clock 22:00 to 6:00 o´clock
!
Attention!
hen the floor heating is activated the standard switching times are put forward for 2 hours!
The heating controller runs a logical standard program for the hot water support: As long as there are no
separate hot water switching times programmed, the hot water support conforms to the switching times for the
heating. That means, the hot water support is activated 45 minutes before night/day-switchover until day/night-
switchover (90 minutes during antilegionella release).
In the automatic modes you can choose individual switching times that define, if, how and when your heating
runs. Move in the submenu by pressing the key until ”CH“ appears on the display. Acknowledge your
choice with the key .
e.g.
For example, you can program your heating system that way, that it heats and supports hot water
between 6 and 7 o´clock in the morning for getting up, is off during the daytime and switches on again
at 16 o´clock in the afternoon for coming home from work. For the weekend you can respectively
define other switching times.
You can define switching times for different switching time channels: desired room temperature, hot water and
circulating pump (if mounted).
hen you are in the submenu switching times, you can first choose the different switching time channels with
the keys and .
