REGULUS - STDC E Controller - www.regulus.eu
F 5 - Settings
The necessary basic settings required for the control
function are made in menu
„5. Settings”
.
The menu is closed by pressing
„esc”
or selecting
„Exit settings”
.
Parameters are set depending on the hydraulic variant
selected.
The following pages contain generally valid settings
descriptions.
F 5.1 - Tmin S1
If this value is exceeded at sensor S1, then the controller switches the associated pump and/or valve on. If the
temperature at sensor S1 drops below this value by 5 °C, then the pump and/or the valve are switched off again.
Setting range: 0-99 °C / default setting: 20 °C
When using hydraulic variant 3 with solid fuel boiler, at least 60 °C should be set. Consider
instructions of boiler manufacturer!
F 5.4 - Tmax S2
If this value is exceeded at sensor S2, then the controller switches the associated pump and/or valve on. If the
temperature at sensor S2 drops below this value again, then the pump and/or the valve are switched off again.
Setting range: 0-99 °C (for hydraulic variants
„Thermostat“
and
„Universal
Δ
T“
this value may be set to Off)
Default setting: 60 °C (for hydraulic variant
„Solar system with pool“
the default setting is off)
Temperature values which are set too high will allow higher solar heat accumulation but it shall be
checked that all system components are resistant to high temperature and scalding protection is
provided. Regulus solar systems are safe for heating water up to 95 °C.
F 5.8 -
Δ
T R1
Switch-on/switch-off temperature difference for relay R1
If the temperature difference
∆
T between the reference sensors is exceeded, then the controller switches
the pump on. If the temperature difference between the reference sensors drops to
∆
Toff, then the pump is
switched off again.
Settings range:
Δ
T from 3 to 20 °C /
Δ
Toff from 2 to
Δ
T minus 1
Default setting:
Δ
T 10 °C /
Δ
Toff 3 °C.
If a too small temperature difference is set, it may happen that the heat source cannot heat up the
consumer to the pump switch-off temperature (Tsource - Toff). Then the pump runs continuously.
