Do you want to save money on water heating or heating? Read on. Do you own a cottage and need to heat water in a boiler in summer and temper the building in winter with an ordinary direct-fired heater? And not pay for energy? The controller is for you too. But beware, the connected device must be purely resistive without additional electronics (display, electronic thermostat, fan, etc.) and must be switched off by a mechanical thermostat.

It is possible to apply for a subsidy from the New Green Savings Programme for photovoltaic water heating with the MR4316AC NG P&P controller.

The MR4316AC NG P&P controller in the Mode 4 cabinet is designed to operate in Mode 4 i.e. automatic back-up heating from the grid if there is not enough energy from the PV panels. The controller is plug and play (P&P) so all you need to do is connect the panels, mains voltage and boiler to it and start heating. All components (MR4316AC NG controller, PN4316 power switch, 16A circuit breaker, two fuse disconnects and terminal blocks) are housed in a common rack and interconnected. A power indicator is located under the cover of the switchboard.

Active cooling or surge protection can be added to the controller. If the components are ordered together with the controller, their installation is free of charge.
