Explanation:
The average inside temperature measurement time
which the room compensation uses.
Return water maximum allowed temperature at which
the regulator begins lowering the return water temp.
Freeze protect limit. Minimum return water temperature
when the outdoor temperature is 0°C.
Maximum district heating output at which output limiting
begins in regulating circuit H1.
Drop in supply water temperature when the exhaust fan
is at ½ speed (see page 32).
The length of time from which the regulator calculates
the HW average temperature for the alarm.
The outdoor temperature limit for relay 1 (in use when
time /outdoor temperature control has been selected for
relay 1's control mode)
Freeze protect limit. Minimum return water temperature
when the outdoor temperature is -20°C.
Lower limit of supply water during a free temperature
drop in the regulating circuits H1/H2 when the outdoor
temperature is 0°C. (stand-by function)
Lower limit of supply water during a free temperature
drop in the regulating circuits H1/H2 when the outdoor
temperature is -20°C. (stand-by function)
Maximum district heating water flow at which output
limiting begins in regulating circuit H1
H1/H2/HW supply water temperature deviation from the
setting determined by the regulator which causes the
alarm
Temp. (meas. 11) deviation from the setting of "R1 Temp
operated" which causes the alarm. This setting appears
if "Temp operated" has been selected in the relay1
control mode (see page 26).
The alarm goes off if the deviation has lasted for the set
time.
