1 - INTRODUCTION
1.1 - CONTROLLER CLIMATIC™60
The new generation of microprocessor based control, CLIMATIC™ 60 may be fitted to the Lennox Chiller or Heat
pump range. It inherits 20 years of technology and field operating experience from its predecessors the
CLIMATICTM1 and CLIMATICTM2 and CLIMATICTM50.
LENNOX has found the latest hardware technology available on the market place and developed software
specifically designed for Chiller and Heat pump applications, maximising the LENNOX unit’s efficiency and
performance.
1.2 - COMPATIBILITY
This documentation is compatible with the programs Chiller and Heat pump:
•ECOLEAN range from software version CH060 STD - Vers. 01.0 - Rev 00.0,
•NEOSYS standards range (STD) from software version CH060 STD - Vers. 01.0 - Rev 00.0.
1.3 - WARNING
Any parameter modification should be carried out by trained and licensed competent technician. Before start-up or
restart of a unit controlled by the CLIMATIC™ 60, it is mandatory to check adequacy between CLIMATIC™ 60 and
the unit with its options. In case of wrong parameters, the inputs / outputs connections could be incorrect and may
create some operation problems for the units and ultimately breakdowns. Lennox cannot be held responsible for
any claims on the units due to a wrong parameters sequence or a parameters modification carried out by non
competent technicians. In this case, the warranty will be legally null and void.

3 - SCHEDULING ZONE
3.1 - Function
The CLIMATIC™ 60 is provided by a real time clock which offers solutions to specify a weekly schedule.
3.2 - Description
The CLIMATIC™ 60 schedule manages up to 7 distinct clock zones per day from 00h00 to 24h00 and from
Monday to Sunday. The zone can start at different time for each day of the week in order to optimise the operating
of the unit.
3.3 - Settings
The different settings to adjust the scheduling zone are available in the menu:
•(2141): Start time of the zone 0 from Monday to Sunday.
•(2142): Start time of the zone 1 from Monday to Sunday.
•(2143): Start time of the zone 2 from Monday to Sunday.
•(2144): Start time of the zone 3 from Monday to Sunday.
•(2145): Start time of the zone 4 from Monday to Sunday.
•(2145): Start time of the zone 5 from Monday to Sunday.
•(2146): Start time of the zone 6 from Monday to Sunday.
Note: The start time can take different values from Monday to Sunday. The start time of the zone 0 must be set to
00h00.

4 - SCHEDULING MODE
4.1 - Function
The CLIMATIC™ 60 is able to control different mode for each zone in order to optimise the operating of the unit.
4.2 - Description
The CLIMATIC™ 60 can manage up to 4 different modes.
4.3 - Settings
The different settings to adjust the scheduling mode are available in the menu:
•(2151): Mode used during the period of the zone 0 from Monday to Sunday.
•(2152): Mode used during the period of the zone 1 from Monday to Sunday.
•(2153): Mode used during the period of the zone 2 from Monday to Sunday.
•(2154): Mode used during the period of the zone 3 from Monday to Sunday.
•(2155): Mode used during the period of the zone 4 from Monday to Sunday.
•(2156): Mode used during the period of the zone 5 from Monday to Sunday.
•(2157): Mode used during the period of the zone 6 from Monday to Sunday.
Note: The mode used can take different values from Monday to Sunday.

5 - SCHEDULING ZONE ANTICIPATION
5.1 - Function
The CLIMATIC™ 60 allows the start up of the unit before the pre-specifyd hour of the first zone (Zone 1) of the day.
5.2 - Description
This function is able to start the unit in zone 1 earlier if the outdoor temperature is under a specify threshold. The
typical application is to start the unit in heating mode if the weather is too cold compare to the actual season.
Example :
•(2142): Start time zone 1 : 8h00,
•(2161): Anticipation foot : 10.0°C,
•(2162): Anticipation gradient: 10mm/°C.
In this example the foot is set to the value 10.0°C, which means the zone 1 will always start at 8h00 if the outside
air temperature is higher than 10.0°C. If the outside air temperature is less than 10.0°C the zone 1 will start
according to the gradient selected and the difference from the foot value and the actual outside air temperature
(10.0 - 7.0 = 3.0 x 10 = 30min). So the new start time for the zone 1 is 7h30.
5.3 - Settings
The different settings to adjust the anticipation are available in the menu:
•(2161): Anticipation foot.
•(2162): Anticipation gradient.

6 - CHANGEOVER HEAT / COOL
6.1 - Function
The CLIMATIC™ 60 control the changeover mode (for reversible units only) to specify the appropriate demand on
heat water or chilled water production.
6.2 - Description
The changeover can also be pre-specify according to the scheduling and can take different mode for each
schedule mode (A, B, C, D, and BMS).
The changeover mode can be set by different solutions:
Automatically:
The CLIMATIC™ 60 determines the appropriate production of the water according to the outside temperature and
move automatically the unit from the cooling to heating mode and heating to cooling mode.
If the outside temperature is below the setting value (3225), the unit will operate as a heat pump.
If the outside temperature is over the setting value (3226), the unit will operate as a chiller.
Manually:
The changeover mode is pre-specifyd for each schedule mode. The various modes available are “Cool” mode,
“Heat” mode or “Dead zone”. In this case the outside temperature has not effect on the changeover mode.
Remotely:
The changeover mode is set according to a remote dry contact connect on a free custom digital input. In this case
the unit swaps in cooling or heating mode according to the status of the digital input. Please refer to the paragraph
“Free Input / Output” for more details.

Terminal DC60:
The changeover mode (cool / heat) can be modified by the terminal DC60 by pressing the “mode” button.
Heat Cool Auto Dead zone
When the “Auto” mode is selected, the icon “Cool” or “Heat” is displayed to signal the actual operating mode. Due
to the communication delay, after pressing the “mode” button it is well advised to wait few seconds, the time to
refresh of the icon on the display.
6.3 - Settings
The different settings to adjust the changeover mode are available in the menu:
•(3224): Changeover mode (Cool, Heat, Auto, Dead zone) for each schedule mode (A, B, C, D, and BMS).
•(3225): Minimum of outside temperature to swap to heating mode. If (3224)=“Auto”.
•(3226): Maximum of outside temperature to swap to cooling mode. If (3224)=“Auto”.
