house indoor temp could not be met

Dear All,

I am using a Air sourced heat pump for a house heat source, with ground floor(heated floor heating), first floor(water convector), and I've changed the outdoor temp always equal to Zero(constant number), and indoor thermostatsetpoint (heating) is set to 25C, simulation running period is whole Jan.

However, when I finish the simulation and looking at the results, it never reach 25C (none rooms).

  1. I am wondering is there any dead band or acceptable range of the desire temperature in EP+, +- 5 degrees?
  2. I've made some changes in the capacity of the heat pumps/fans, but it did not seems could increase the temp.

Many thanks for your help. Nancy
