Zone hydraulic units THERM SIM

Heating circuits:

1 ÷ 3 zones

The SIM zone hydraulic unit ensures a simple and elegant connection of the heat source to the heating circuits. The built-in automatic regulation system ensures problem-free operation of the multi-circuit heating system. It can be used when combining circuits with heating bodies and the floor heating, which is the requirement of most modern heating systems.

We supply three different types of zone hydraulic units:

SIM 3Z-21 - two mixed circuits + one not mixed; the unit can regulate three independent heating zones
SIM 2Z-20 - two mixed circuits; the unit can regulate two independent heating zones
SIM 2Z-11 - one mixing circuit + one not mixed; the unit can regulate two independent heating zones

Each type of solution can be supplied with a Honeywell SZ 10004 built-in zone regulation unit.
