Electrical connection
Requisite user qualification:
ELECTRICAL SPECIALIST
Electrical connection of filter pump control may only be
performed by an ELECTRICAL SPECIALIST as
defined in the chapter
User qualification.
IMPORTANT NOTICE!
Observe maximum flows
Observe the maximum permissible currents for the sum
of all relay switch outputs being used in 230V~ (in sum,
max. 4A).
Please also refer to the Chapter
230V~ Power supply.

Overview
PoolManager
®
offers the capacity to trigger a heating system.
The heating system is triggered via a simple relay switch output
(potential free or 230V~). The exact type and design of the heating
system is not important. There only needs to be a possibility to turn the
heating function on and off externally via a corresponding input.
INFO
Toggle switch OUT 4 [31/32]
If you need a toggle switch for heating control, you can
use the relay switch output OUT 4:
•
[31b] Working contact
•
[32c] Resting contact
27.2
Temperature measurement
Heating control requires measurement of the water temperature.
PoolManager
®
three temperature inputs can be used to do so.
You'll
find
a
detailed
description
in
the
chapter
Temperature measurement.
It has all the sensor types supported by
PoolManager

.
IMPORTANT NOTICE!
Measurement precision of the standard
temperature sensor in the measurement chamber
The standard temperature sensor in PoolManager
®
measuring cell can fundamentally be used for
temperature measurement. It represents a very simple
solution, as there is no need for additional installation
work.
However, note that the temperature measured in the
measuring cell may deviate from the actual pool
temperature. Changes in air temperature, sunshine, or
other influences, the water may heat up or cool down
along its path through the measurement water circuit.
Calibration cannot compensate for these effects, which
fluctuate over time.
For this reason, the measurement precision to be
expected of the standard temperature sensor is
generally too marginal for reliable temperature
measurement and control.
For controlling the heating system, you should
therefore definitely install an additional sensor directly
in the circulation circuit whose measurement. That
sensor's measurement signal needs to be independent
of external effects and representative for pool
temperature.
27.3
Function
The desired temperature setpoint and a add-on switch hysteresis can
be configured as parameters.
The setpoint temperature should be configurable in a range between
10.0°C and 40.0°C.
Hysteresis ensures that heating control does not turn on and off for
marginal temperature changes, rather only when there is a certain
deviation from the setpoint.
Hysteresis is configurable in a range between 0.1°C and 5.0°C.
This temperature setpoint and the temperature hysteresis yield the
temperatures at which heating control turns on and off as follows:
Turn-on temperature
Temperature setpoint minus half of hysteresis
Turn-off temperature
Temperature setpoint plus half of hysteresis
