Services for IQHeat
Cetetherm has developed several services to be able to offer enhanced functionality for the substation.
Cetetherm works continuously on developing new functions and improving old ones, to simplify the handling of
IQHeat and provide the ability to monitor and optimise plants.
Good comfort and lower energy consumption can be combined and monitored using IQHeat.
Many functions are always included in an IQHeat. In addition to factors such as internal display, ModBus
communications, easy WEB and pump control, there are several other functions that come with the basic
package.
Services related to an additional hardware or software and that can be ordered as an option.
Communication in the basic package for IQHeat is ModBus RTU, a modem port and a simple WEB. You can
also use ModBus IP through the WEB function.

the Internet to monitor remotely. Option for OPC is available in this basic version of WEB.
