1.14 Te / Tc Setting

You can alter the value of targets Te (evaporating pressure equivalent temperature) and Tc (condensing
pressure equivalent temperature) with setting mode 2. PI control is used to control compressor capacity so
that Te when cooling and Tc when heating are constant.
∗ Target Tc becomes 3˚C higher when indoor load is large. Target Tc is controlled in accordance with the
following conditions:

Te setting
High
Standard
Low
Target Te changes according to compressor operating frequency, length of piping and indoor load. The
range is -10˚C ≤ target Te ≤ 5.5˚C. (Piping length is determined automatically during oil return
operation.)
Tc setting
High
Standard
Low
Outdoor temp. > 10˚C → target Tc ≤ 46˚C
Outdoor temp. ≤ 10˚C → target Tc ≤ 49˚C
Target Tc
= 43˚C when high pressure > 17 kg/cm² (1.67 MPa) and low pressure < 1.8 kg/cm² (0.176 MPa).
