RESOL DeltaSol Plus
Universal temperature differential regulator with
integrated calorimeter
Mounting instructions
Precision-platin-temperature sensors Pt1000 (FKP and
FRP) are used for the RESOL DELTA Pro.
The arrangement of the sensors is of great importance to
the total efficiency of the regulator. The collector
temperature should be measured in the upper part of the
collector. In stores with own heat exchanger, the sensor
must be directly mounted in the upper part of the heat
exchanger. By using external heat exchangers, the sensor
must be fixed at the bottom of the store. For individual
operation systems, our product range contains 3 different
types of sensors (sensors for installation in present
immersion sleeves, flatscrew sensors or cylindrical clip-on
sensors). The sensor types FK and FR have the same
electrical features and are available in the same models,
They only differ in the connecting cable:
2.Sensor types
Standard temperature sensors: for installation in present
immersion sleeves (they are included in complete packages)
FKP6 or FRP6: 6 mm, Pt1000
Immersion sensors: available in different length
(=immersion depth)
FKP60: 60mm immersion depth, chromium-plated copper
FKP150: 150mm immersion depth, chromium-plated
copper
Important: The sensors must be completely pushed into
the sleeve and the nut must be slightly tightened.
Cylindrical clip-on sensors: for any pipe diameter, cpl.
with fastening collar
FKP20 or FRP20
Ensure good thermal contact of the sensor with the pipework
by cleaning the contact area and by applying heat conduction
paste between sensor and pipe. In order to protect the sensor
cable against outside temperature influences, it is
recommended to insulate the pipe.
Flatscrew sensors: for installation on flat surfaces
FKP8 or FRP8
Ensure good thermal contact. Use conduction paste and
insulate the sensors against outside temperature influences.
Indication:
In order to avoid overvoltage damage at the collector (e.g.
by lightening), it is highly recommendend to use the
overvoltage protection RESOL SP1.
FK... : collector sensor
FR... : reference sensor (store sensor)
FK: 1,5 m weather- and temperature resistant silicone cable
for temperatures between -50 °C ... +180 °C, mostly used for
collectors.
FR: 2,5 m PVC cable for tempertures between
-5 °C ... +80 °C, mostly used for stores.
Make sure that all electrical works are carried out according
to the relevant local and IEE-regulations. The sensor cables
carry low voltages and they must not run together in a
cable conduit with cables carrying higher voltages than 50
Volt. By using longer cables or cable conduits, please use
screened cables. The seensor cables can be lengthened up
to 100 m, but the cross section must be 1,5 mm² (or 0,75
mm² up to a cable length of 50m); screened cables should
be used preferably. The sensors must not get directly in
contact with water, please use always immersion sleeves.
