Page 4: General Notes
GENERAL NOTES 1.1 PERMITTED USE The touch screen remote control panel allows the centralized management of a network of chiller/heat pump. 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). 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. -
