Block Pool

This control element shows and operates a swimming pool: at a glance the water temperature, how far the filter pump has already got with its daily target and what the system is doing at the moment. In the dialog the filter pump, the cover, the backwash and the light are operated and the setpoints for heating and water care are set.

Operation

1. State: what the system is doing at the moment. If several things apply, the most important one appears, in this order: Water shortage, Fault, Backwash, Rinse, Frost protection, Cover moving, Catch-up, PV surplus, Filtering, Winter operation, Locked, Maintenance due, otherwise Ready.
2. Pool symbol: shows what the tile is about.
3. Ring: fills with the share of the daily running time the filter pump has already reached today. Without a known daily target it stays empty.
4. Centre: the water temperature, with a fault an exclamation mark. If there is no water sensor, the pool symbol is shown here.

The colour shows the state: blue the filter pump is running, orange a backwash or the frost protection is running, red means fault or water shortage. Otherwise the ring has the font colour. On the basic screen only the ring is shown. A tap on the element opens the dialog.

The dialog

1. Clock: the switching times, see below.
2. Presence: how much of the daily running time applies per presence state, see below.
3. Chart: the running time of the filter pump per water temperature, see Runtime.
4. Gear: setpoints and maintenance, see Settings.
5. Automatic / On / Off: the operating mode of the filter pump. The lit button shows the current one. With Automatic the system filters on its own according to its daily target. On and Off stay until Automatic is selected again or the operating mode at the input of the block changes.
6. Cover open / Cover close: moves the cover; the lit button shows whether it is open or closed. These buttons only exist if a cover is set up.
7. Backwash / Light: Backwash starts a backwash and is lit while it runs, including the rinse. Light switches the lighting on and off and is lit while it is on.
8. Acknowledge: only appears while a fault is present, and resets it.
9. Measured values: the state, today's runtime against the daily target in hours, pH and redox value as well as water and collector temperature. A dash means that this sensor does not exist in the system.

A pressed button lights up briefly until the controller has taken over the command. OK closes the dialog.

Switching times and presence

Behind the clock are the switching times. Each one triggers an action: Filter pump on or off, Backwash, Cover open or close, Lighting on or off and Automatic; a tap on the value steps through them. The actions for the cover only exist with a cover. A newly created switching time is set to No action and switches nothing. Filter pump on and off act like the buttons in the dialog and stay until a switching time with Automatic comes – the daily filter time needs no switching times, the block computes it itself.

Under Presence, for each state – present, absent, holiday – the share of the daily running time from 0 to 200 % is given: 100 % leaves the running time unchanged, 50 % halves it. A tap on the symbol switches the setting for this state on and off, a tap on the value opens the input. By default no state has a setting, so the full running time always applies. How switching times and presence are operated is described under Presence and Block Time switch.

Runtime

1. Water temperature: tap and enter the temperature (0 to 40 °C).
2. Hours per day: the pump filters this long on a day with this water temperature (0 to 24 h).

Between two rows the controller interpolates linearly, below the first and above the last row its value applies. The rows should be in ascending order of temperature. The defaults range from 16 °C with four hours to 28 °C with ten hours. Save transfers the values to the controller.

Settings

1. Setpoints: Setpoint reheating is the water temperature the auxiliary heating heats up to (10 to 40 °C, default 26 °C). Setpoint pH (6 to 9, default 7.2) and Setpoint redox (400 to 900 mV, default 700 mV) are the targets of the dosing.
2. Maintenance after: after this many operating hours of the filter pump the system reports “Maintenance due”. 0 switches the message off, which is the default.

The values are only transferred to the controller with Save. They are stored there and survive a restart.

Setup

This section is meant for the installer of the system.

The control element is linked to the function block Block Pool: first create the function block and assign addresses to its inputs and outputs, then right-click the control element and select the function block. The addresses are taken over in the process and the text is set to the name of the block. Without a link, a tap on the element points this out.

Whether there is a cover is determined by the parameter Cover (Abdeckung) of the block. When heating and dosing take place also depends on the parameters Hysteresis auxiliary heating and Tolerance pH / redox: heating starts as soon as the water is the hysteresis below the setpoint and runs until the setpoint is reached; dosing only starts with a deviation larger than the tolerance. The runtime curve only applies with a linked water temperature, otherwise the parameter Runtime per day.

Parameters

Address links

The addresses come from the link with the function block and need not be entered by hand:

Important: the measured values are read from the addresses at the inputs of the block. If an input is only wired internally to another block, the sensor counts as not present for the display.
