Hydrokit for ECOi. Water at 45 °C

This Hidrokit module provides Hot-water by using waste heat that is recovered from standard air-conditioning indoor unit in cooling mode
Total system performs high energy efficiency by this heat recovering operation, and it gives an advantage for the environmental-friendly assessment scheme (ex. BREEAM in UK).
Connect the Hydrokit to your VRF system, together with other indoor units.

Technical focus
  • Only with 3-Pipe ECOi MF2 6N Series outdoor units
  • Remote controller CZ‑RTC5B common use with DX Coil indoor units ECOi and PACi

Hydrokit control function / CZ‑RTC5B
  • CZ‑RTC5B is updated version from CZ-RTC3. It can be used for hydrokit and also normal indoor unit. CZ‑RTC5B checks the type of connected unit and switch hydrokit or air conditioner style of display automatically
  • Operating  mode on hydrokit style to be set at initial setting of the system from following modes: tank mode or air conditioning mode
Basic principle & advantage
Hydrokit module provides hot water by using waste heat that is recovered from standard air-conditioning indoor unit in cooling mode.
Total system performs high energy efficiency by this heat recovering operation, and it gives an advantage for sustainability related assessment methods, such as BREEAM in UK.

Overview: hydromodule in VRF system
