GENERAL NOTES
1.1
PERMITTED USE
Hi-T2 is a touch screen remote control panel for centralised management of a network of chillers/heat pumps and RFC system. It
can also be used for partial functions (i.e. as a remote control panel of a single chiller/heat pump or ambient temperature
thermostat for managing the different zones).
It includes humidity and temperature sensors for the thermo hygrometric analysis of the environment and for the management of
the double set point for radiant floor heating systems that use a dehumidification system.
The intuitive interface simplifies the use of the controller; all the functions can be easily set through the use of an easy to
understand synoptic.
The remote control supervises and periodically examines the network, there is a cycle time that elapses between the signalling or
command request and the activation of the function, the cycle time depends on the size of a network of fan coils and heat pumps.
For multi-circuit units, only the resources and parameters of the first circuit are displayed.
