R003 – Booster set for high/low direct temperature

High/low direct temperature control unit, suitable for systems with radiators, fan coils and heated towel rails. The circulator, with 1½-inch connections, is available in either an asynchronous (not available for sale in the EU) or electronic version. The pump set features two ball shut-off valves with built-in thermometers for instantaneous reading of flow and return temperatures (the return ball valve includes an integrated check valve) and a ball valve to isolate the circulator. The pump set can be ordered without a circulator or with the flow circulator on the right; the circulator can be easily moved to the left. The set is supplied with a black EPP insulation shell.
