IvarSAT satellite modules can be divided into three groups, which are different in the type of heating systems each of them is suitable to supply:
- Family H, suitable to high-temperature systems: one heating circuit with zone valve;
- Family L, suitable to low-temperature systems: one heating circuit with three-way mixing valve, zone valve and variable-speed booster pump;
- Family HL, suitable to high- and low-temperature systems: one heating circuit with three-way mixing valve, zone valve and variable-speed booster pump; a second heating circuit with zone valve.
Among the several variants, additional features are available such as domestic hot water recirculation circuit and a "direct" second outtake for non-mixed domestic hot water. IvarSAT is available either on frame or already housed in recessed or wall-hung box. As an alternative, it is possible to purchase the connection template and the hydraulic modules to be installed after the test. As concerns measurement devices, it is possible to choose among different kits suitable to any type of reading (direct, central via M-BUS or central via RADIO network). All devices are MID compliant and feature supplementary metrology marking.
