OPTION FOR DOMESTIC HOT WATER
An optional application, mainly designed for the hotel industry, high-temperature hot water produced on a primary circuit and sent to a domestic hot water (DHW) preparer can be guaranteed solely by the GAS module boiler During use, this primary water circuit, independent of the heating or air conditioning circuit, will be entirely devoted to producing DHW using natural gas, in "accumulation" or "semi accumulation" mode, with the heat pump continuing to run during when its control is switched between COOLING and HEATING mode. The integration of a hydraulic compensator inside the module helps eliminate pressure drops in the primary network between the gas module and the DHW preparer: - the boiler accelerator pump guarantees operation between the boiler and the hydraulic compensator, - on the installation side, an accelerator pump guarantees the primary water flow between the DHW preparer and the gas module.
Note: - The water temperature at the mixer tank outlet to the DHW preparer will be hotter the closer the primary accelerator pump flow rate is to that of the boiler. - Obtaining a hot water temperature at the heat pump outlet as close as possible to that at the boiler outlet will therefore be conditioned by having the lowest possible difference between these two flow rates.

DHW option with GAS
The production of high temperature water by the Hybrid heat pump is controlled by an on/off input or via a BUS link provided by the operator, and switches the 3-way valve on the primary circuit to DHW production. The user can activate a parameter to enable the control to order the DHW cycle to stop, in cooling mode or heating mode, according to the following criteria:
- Priority DHW: priority is given to the DHW cycle within the cycle's maximum time limit, - Comfort DHW: the DHW cycle is started whilst monitoring the minimum water return temperature for the heating circuit, to reheat it if necessary.
