KLIC-DA LT 

The KLIC-DA LT  application program provided by Zennio  focuses on controlling 

Altherma LT

 (from 

Low Temperature

) systems, in contrast to the 

Altherma HT

 (from 

High Temperature

) systems. 

An Altherma LT system consists of a series of elements (an external unit, a hydrobox, 
an internal unit, the user interfaces, etc.), and the specific “P1/P2” communication bus, 
which allows the user interfaces (typically, one acting as the 

main

 control and the other 

as an 

additional

 control) communicate to each other and to the Altherma system. 

Note

only the main interface interacts with the Altherma LT system. Any order from / to 

the additional interface will reach the main interface too

KLIC-DA is meant to 

replace the aforementioned additional

  interface, and  thus  to 

communicate only to the main interface and not to the Altherma LT system directly.  

The main functions performed by the KLIC-DA LT application program are: 

  Management of the 

domestic hot-water

 (DHW) system. 

  Management of the 

room

 

climate

 system (Leaving Water Method). 

 

Error handling

  Simultaneous  monitoring  of 

multiple  indicators 

(temperature  setpoints, 

actuator states, sensors…) reported by the Altherma system. 

On the other hand, Altherma LT systems feature three climate control methods: 

  Control of the

 leaving water temperature

 (LWT), 

  Control through a 

user interface

 configured as a thermostat, 

  Control though an 

external thermostat

 (TH). 

The KLIC-DA LT  application program is only compatible with Altherma LT systems 
configured for an 

LWT control

, and with 

only one climate zone

 (Altherma LT systems 

permit up to two climate zones with independent setpoint temperatures).
