Mitsubishi Ecodans ASHP issues...

[Jon Glanfield]

I rang Ecotec about these units, the guy I spoke to didn't know anything about them and said he would ask someone more senior to ring me, he hasn't to date.....................

[Bigfreeze]

Jon, don't you know the technology behind these things is so top secret that they can't even tell their customers!!

[MikeHolm]

shhhh, he is not supposed to know about the monkeys

[TiredGeek]

Guys, could this be my problem? The monkey has frozen to death?????

[MikeHolm]

You were probably feeding him too many bananas and the condenser got clogged.

[Bigfreeze]

I think t'was the monkeys that installed yours tiredgeek

[MikeHolm]

It is all a question of energy in/energy out...the monkeys cannot eat frozen bananas so they throw them at the condenser causing massive damage and since there is no input of energy to the monkeys they freeze to death. BF cannot take his shower and Tiredgeek gets to do a service call but it is a big problem because the monkeys were supposed to be shipped from Ireland and somehow 2 and 2 were not put together as it was a bank holiday so Tiredgeek (TG for short) could not do his service call as the supplier did not have a set of replacement monkeys and BF had cold showers for....ohh maybe 3 or more days as the courier somehow decided it was better to go watch the Isle of Mann TT (he got side tracked). No idea where the monkeys are now.

Comments on the technical aspects of this system are appreciated

Most units in the industry which are market leaders use algorithms which are calculated, this works on compressor frequency, time, outdoor ambient, condensing temperature and more than one sensor on the outdoor coil.
The termination is a combination of head pressure control, coil temperatures and on a wet system peak freeze can also terminate the defrost, peak freeze is a protection which terminates a defrost in teh event the system does not have enough water flow through the plate heat exchanger to stop it freezing.
