D 5.17 - Teco S3 Minimum temperature S3 in Energy saving mode
If the temperature at sensor 3 falls below this value and the thermostat function is active (see 5.14), additional
heating via relay R2 is switched on.
Additional heating is on until Teco S3 + hysteresis is exceeded.
Teco
Setting range: 0 °C - 99 °C / default setting: 20 °C
Example: Limitation of additional heating temperature in storage tank with el. heating rod.
Hydraulic variant B18 Solar system + zone valve + thermostat shall be selected.
Relay switching the el. heating rod shall be wired to R2.
1) With the default setting valid, i.e.energy saving mode off (Tset S3 = 50 °C, hysteresis = 10 °C, thermostat
operation period = 06:00 to 22:00), the el. heating rod heats the storage tank to a temperature between
60 °C (on) and 70 °C (off) during the period from 6:00 to 22:00, independent of solar heat.
2) If the Energy saving mode (5.16) is active and Teco = 20 °C, then:
If solar heat is available, then between 6:00 and 22:00 el. heating rod heats the storage tank to 20 °C
(on) - 30 °C (off).
If no solar heat is available, then the el. heating rod heats the storage tank to 60 °C (on) - 70 °C (off)
between 6:00 and 22:00, like in normal mode.
