6. Operating modes

6.1. Operating mode M1: Hot water

6.1.1. Explanation

In this operating mode, an electric heat generator is supplied continuously with excess PV. If a bimetal thermostat is present, the SOL•THOR switches off via this when the preset temperature is reached. Alternatively, the my-PV temperature sensor can be used.

6.1.2. Optional hot water boost function

Optionally, the SOL•THOR can also maintain a minimum temperature. Two boost modes are available in operating mode M1. See "Specific settings for operating mode M1".

6.1.3. Specific settings for operating mode M1

WW 1 Temperatures
The maximum temperature that may be reached at the my-PV temperature sensor can be set here (the factory setting is 60 °C). This has no influence on any bimetal thermostat that may be present.

The optional automatic temperature boost backup can be set to the right of the temperature setting. It is only possible to enter a minimum temperature if AC has been connected and the boost function has been activated (factory setting: Off). The factory-set minimum temperature is 50 °C. The backup boost can be set to "On" or "Relay"

Automatic temperature boost backup "On":
When active, the heating rod at the electronics is supplied with maximum power.

Automatic temperature boost backup "Relay":
Alternatively, the minimum temperature can be maintained by enabling an external heat source. For details of wiring the potential-free contacts, please refer to the chapter "Boost Relays".

The selection of the following setting: "WW1 min switching times"," WW 1 min weekdays" and the "Legionella mode" is only possible if the backup boost setting is not "Off" under "WW 1 temperatures" and AC is connected.

WW 1 min Switching times
This setting can be selected if the temperature safety setting is not "Off" under "WW 1 temperatures".

Two time windows are available to maintain the minimum temperature. The start and end times can be specified in full hours. The default switching times are as follows: 5 pm - 11 pm and 5 am - 7 am.

Tip

We recommend limiting the times when the minimum temperature should be maintained to the morning and evening hours in order to increase PV self-consumption during the day.
If you only want to use the BOOST button, enter 0 in all fields of the two time windows.

WW 1 min Weekdays
You have the option of selecting the days of the week on which the minimum temperature should be maintained. All days of the week are activated by default.

Legionella mode
To ensure drinking water hygiene, a time period can be specified by which a defined minimum temperature must be reached again after the last time this value was reached at the internal sensor T1. The number of days of this period can be set between 1 and 14. It is possible to specify a time for the start of the legionella programme. The factory setting is for a period of seven days, the legionella programme starts at 8 p.m., the target temperature is 60 °C and the programme is deactivated.

The SOL•THOR is supplied with maximum power until the target temperature set for the legionella mode at sensor T1 is reached. Please note that electricity is drawn from the mains in this context.

6.2. Operating mode M2: Hot water stratified charging

6.2.1. Explanation

In this operating mode, two electric heating rods in a storage tank are supplied with PV energy in turn and in an infinitely variable manner. The upper heating rod has priority. The aim is to reach the desired temperature as quickly as possible at the tapping point, before any further surplus warms the rest of the storage tank contents. As soon as the upper heating rod has reached the target temperature, the lower heating rod is supplied. If the my-PV temperature sensor is not used, the changeover is done via the thermostats of the heating rods. The SOL•THOR then periodically monitors whether the upper heating rod is available again. When using the my-PV temperature sensor, the changeover occurs as soon as the temperature at the sensor reaches the set maximum value.

Tip

It is also possible to control two heating elements in different storage tanks. The "upper" heating element is then located in a drinking water cylinder, for example, and the "lower" heating element in a buffer cylinder next to it. However, the temperature sensor is essential and must be installed above the "upper" heating element!

6.2.2. Optional boost backup

Optionally, the SOL•THOR can also ensure a minimum temperature at the external sensor T1.
See "Specific settings for operating mode M2".

6.2.3. Specific settings for operating mode M2

Automatic temperature boost backup "On":
When active, the heating rod at the electronics is supplied with maximum power.

WW 1 min Switching times
This setting can be selected if the temperature safety setting is not "Off" under "WW 1 temperatures".

Two time windows are available to maintain the minimum temperature. The start and end times can be specified in full hours. The default switching times are as follows: 5 pm - 11 pm and 5 am - 7 am.

Tip

We recommend limiting the times when the minimum temperature should be maintained to the morning and evening hours in order to increase PV self-consumption during the day.
If you only want to use the BOOST button, enter 0 in all fields of the two time windows.

WW 1 min Weekdays
You have the option of selecting the days of the week on which the minimum temperature should be maintained. All days of the week are activated by default.

The SOL•THOR is supplied with maximum power until the target temperature set for the legionella mode at sensor T1 is reached. Please note that electricity is drawn from the mains in this context.
