5.11 Water Heating
Water Heating operates according to temperature within a set time frame (between start “From Time” to end “To
Time”) and can be used to increase irrigation water temperature or prevent frost.
• From Time (hh:mm): Set the start time of the water-heating program.
• To Time (hh:mm): Set the end time of the water-heating program.
• Water Temperature: Water heating will be activated when the temperature drops below this value.
• Difference: Dead-band for stopping water heating. When the water temperature reaches the set Water
Temperature + Difference, water heating will be stopped.
For Example: Water temperature is 25ºC and the difference is 2ºC. Water heating will start when the
temperature drops below 25ºc and will stop when it is 27
o
or above.
The Minimum difference is 0.3ºC and the default is 0.5ºC.
• Temp. Sensor 1/2: Assign up to 2 temperature sensors. If you assign 2 sensors, the NMC-Pro will operate
according to their average.
