DIY Inverter Mitsubishi SRK25ZIX-S heat pump

[lutti]

Hi,
Is it possible to convert air of Mitsubishi SRK25 ZRX-S to water-heat pump? I want to
control the work of that pump with the original control circuit of an inner part of
a condensing unit?
The problem is with the speed indicator of the fan. Is there anybody who has got
such an experience?

Lutti,

I am sorry, this is not meant to be direspectful, but I am not sure what your question is. Are you asking if a standard AC/heat pump air to air can be converted to air to water? If so the answer is yes with an appropriate heat exchanger.

Hello Fridge Doctor,
i have already done what you mean. but now i want to convert inverter air to air heat pump to water system. i have all the details for this project including a plate heat exchanger. The problem is that the indoor unit controls a fan speed and gets a feedback signal from this fan. Maybe there is any testmode , jumper, or something that i can switch this rotor feedback off!
