After compressor start running, when ‘setting return water temperature – actual return water temperature
constant temperature setting, and the electrical heater does not start, then enter constant temperature control
The temperature and its frequency during constant temperature program. Recorded by the above chart
ƸT=T1-Ts+2ć, ƸT has 10 areas, from 0 to 9, the rule of constant
a)
when
ƸT is changing
i) When
ƸT is increasing, the frequency increase 1 to run
ii) When
ƸT is decreasing, the frequency decrease 1 to run
b)
when
ƸT stay at a area as 3 minutes, the rules as follow:
