4.14. Energy measurement
4.14.1. Settings for energy measurement
Description
 This is a function to measure the thermal energy received and sent with liquid in cooling and heating system.
 Energy measurement can be started by setting MODE to “USED” and input signal to “Pt100”.
 Instantaneous energy can be output as analog signal. See section 4.12.1. for more detail.
 Totalization can be divided into heating totalization and cooling totalization. In addition, totalized pulse can be output. See section
4.12.1.
 Status (alarm, energy flow switch, energy total switch, etc.) can be output. See section 4.12.3.
 Settable range:
1. MODE : NOT USED, USED(factory set)
2. OPERATION : COOLING(factory set)
COEFFICIENT
(1.000 to 9.999 (factory set: 4.186))
HEATING
COEFFICIENT
(1.000 to 9.999 (factory set: 4.123))
AIR-CONDITIONING
CHANGE TEMP.(-40 to 200°C
（
factory set: 30°C)
TEMP.HYS (-40 to 200°C (factory set: 25°C)
3. INPUT SIGNAL : NOT USED, Pt100 (factory set)
4. SUPPLY TEMP. :TS INPUT
CALIBRATION ZERO (-40 to 40°C (factory set: 0°C))
CALIBRATION SPAN (50 to 150% (factory set: 100%))
DAMPING (0 to 120sec (factory set: 5sec))
SETTING
TEMPERATURE (-40 to 200°C (factory set: 25°C)
5. RETURN TEMP.: TR INPUT
CALIBRATION ZERO (-40 to 40°C (factory set: 0°C))
CALIBRATION SPAN (50 to 150% (factory set: 100%))
DAMPING (0 to 120sec (factory set: 5sec))
SETTING
TEMPERATURE (-40 to 200°C (factory set: 25°C)
<Note> When temperature difference is 0.5°C or less, thermal energy is indicated as zero.
Minus-totalization is not available when the direction of flow is reverse.
