RESOL DeltaSol Plus
Universal temperature differential regulator with
integrated calorimeter
Mounting instructions
4.5 Adjusted values:
The selection of the control prameters or the regulation
default is to be made in the adjusted values menu:
Tstmax: maximum temperature for the store
DTon switch-on temperature for relay 1
DToff switch-off temperature for relay 1
DT2on (only version flowmeter)switch-on
temperature for relay 2
DT2off (only version flowmeter)
switch-off temperature for relay 2
T-Thon (only version flowmeter)switch-on
temperature for thermostat function
T-Thoff (only version flowmeter)switch-off
temperature for thermostat function
All available additional options can be activated or
desactivated by replying (Y)es or (N)o in the options menu:
Tube col: Switch-on logic for improvement of the
turn-on characteristics of systems with
infavourable placed collector sensor -
prevents a delayed switching on of the
system. The collector circuit is switched on
every 30 min. for a period of 30 sec.
Collector cool.: If the collector temperature rises
above the adjusted maximum collector
temperature (120 °C), the pump remains
activated until this temperature limit value
is again underrun.
Recooling: If the maximum store temperature is
exceeded, the solar pump is switched on
for cooling purposes in order to avoid an
overheating of the collector. The
temperature of the store can rise, but only
up to 90 °C (security swich-off of the
store).
Frost protection: As soon as the temperature falls
under 4 °C, warmer water from the store
will be pumped into the collector in order
to avoid frost damages. If a temperature of
5 °C is reached at the collector, the pump
is switched off again.
Indication: this function is only
appropriated for countries with few days
of temperatures at freezing point.
4.6. Options
t-Thon (only version flowmeter)
switch-on time for thermostat function
t-Thoff (only version flowmeter)
switch-off time for thermostat function
Tcollmax: maximal temperature of the collector
Tkolnot: limit temperature for switch-off of the
installation
Tcollmin: minimal temperature of the collector
Vol./Imp.: volume per impulse of the flowmeter
Flow: actual flow in l/min
Frostschutz: glycol fraction in %
Min.-speed: minimal speed for relays
Time: actual time
WMZ: Activation of the integrated
calorimeter.
(only version flowmeter)
Minimal: Activation of the minimal temperature
limitation of the heat source
Ext-heat exch.: Relay 2 is switched on (speed
regulated) if the regulated switch-on
temperature difference is exceeded
and the solar pump is working. It is
again switched off when the
temperature difference is under the
regulated switch-off temperature.
DT R2: Relay 2 is switched on if the relative
switch-on temperature difference is
exceeded and is again switched off
when the temperarture difference
is under the regulated switch-off
temperature. (only version flowmeter)
After heating: Use of relay 2 for a thermostat
function with to be regulated switch-
on and swicht-off temperature.
Valve: When the option Ext-WT is used and
if this option is activated the speed
regulation for relay 2 is desactivated.
only version flowmeter
