Control heat pump with Sensors and Switch

[fernandojsdias]

Hi Everyone,

Greeting from Portugal, I am new here at the forum and I need some help, so I have a heat pump (Saunier Duval SDHV19) and the energy consumption is a little bit high (30Kw/day), a year ago the consumption was worst, like 90Kw/day, after reading the manuals I saw that the thermostats could be used also on the interior, so I change all the parameters to use in the interior and the truth is the consumption decrease for almost 1/3, I guess is not enough, so that's why I am here, my idea is to use interior Temperature sensors in every room and somehow (average temperature of all rooms for example) control the heat pump.
Do you think that this is possible?
