3.1.6 Heat quantity balancing

OHQM:Heat quantity balan-

cing Adjustment range: OFF ... ON Factory setting: OFF

A heat quantity balancing is possible for all systems in conjunction with a ﬂowmeter. You just have to activate the option heat quantity balancing in the channel OHQM.

The volume ﬂow readable at the ﬂowmeter (l/min) must be adjusted in the channel FMAX. Antifreeze type and concentration of the heat transfer medium are indicated on the channels MEDT and MED%.

Type of antifreeze:

0 : water 1 : propylene glycol 2 : ethylene glycol 3 : Tyfocor® LS / G-LS

FMAX: Volume ﬂow in l/min Adjustment range 0 ... 20 in steps of 0,1 Factory setting 6,0

kWh/MWh:Heat quantity in kWh / MWh Display channel

MEDT: Type of antifreeze Adjustment range 0 ... 3 Factory setting 1

MED%: Concentration of antifreeze in (Vol-) % MED% is blinded out by MEDT 0 and 3. Adjustment range 20 ... 70 Factory setting 45

The heat quantity transported is measured by the indication of the volume ﬂow and the reference sensor of feed ﬂow S1 and return ﬂow S4. It is shown in kWh-parts in the indication channel kWh and in MWh-parts in the indication channel MWh. The sum of both channels form the total heat output.

The heat quantity added up can be reset. As soon as one of the display channels of the heat quantity is selected, the

symbol is permanently shown on the display. The button SET (3) must be pressed for approx. 2 seconds in order to get back into the RESET-mode of the counter. The displaysymbol is ﬂashing and the value for heat quantity will be set to 0. In order to ﬁnish the RESET-procedure, the button

must be pressed for conﬁrmation.

In order to interrupt the RESET-procedure, no button should be pressed for about 5 seconds. The controller returns automatically into indication mode.

3.1.7 ∆T-regulation

Please note: Switch-on temperature difference DO must

be at least 2 °Ra higher than the switch-off temperaturedifference DF.

DT O: Switch-on temperature Adjustment range 2,0 ... 40,0 °Ra Factory setting 12.0

DT F: Switch-off temperature diff. Adjustment range 1,0 ... 38 °Ra Factory setting 8.0 °Ra

Primarily the controller works in the same way as a standard differential controller. If the switch-on difference (DT O) is reached, the pump is activated. If the adjusted switch-off temperature is underrun (DT F), the controller switchesoff.

3.1.8 Maximum tank temperature

If the adjusted maximum temperature is exceeded, a further loading of the tank is stopped so that a damaging overheating can be avoided. If the maximum tank temperature is exceeded, on the display is shown and .

Please note: The controller is equipped with a securityswitch-off of the tank, which avoids a further loading of the tank if 203 °F are reached at the tank.

S MX: Maximum tank temp. Adjustment range 40 ... 205 °F Factory setting 140 °F

CMX: Maximum collector temp. Adjustment range 210 ... 380 °F Factory setting 250 °F

3.1.10 System cooling

If the adjusted maximum tank temperature is reached, the solar system switches-off. If now the collector temperature raises to the adjusted maximum collector temperature (CMX), the solar pump remains activated until this limit temperature value is again underrun. The tank temperature might continue to raise (subordinated active maximum tank temperature), but only until 203 °F (emergency shutdown of the tank). If the tank temperature is higher than the maximum tank temperature (S MX) and the collector temperature is lower by at least 5 K than the tank temperature, the solar system remains activated until the tank is again cooled down by the collector and the tubes under the adjusted maximum temperature (S MX). In case of active system cooling on the display is shown (ﬂashing). Due to the cooling function the solar system can be kept operable for a longer period on hot summer days and a thermal release of the collector and the heat transfer medium is ensured as well.

OCX: Option system cooling Adjustment OFF ... ON Factory setting OFF

3.1.9 Limit collector temperature Collector emergency shutdown

If the adjusted collector limit temperature (EM) is exceeded, the solar pump (R1/R2) is deactivated in order to avoid a damaging overheating of the solar components (collector emergency shutdown). The limit temperature is set to 285 °F but it can be changed within the adjustment range of 230 ... 400 °F. In the display is shown (ﬂashing).

EM: Limit collector temperature Adjustment range 230 ... 400 °F, Factory setting 285 °F

3.1.11 Option minimum collector limitation

OCN:

Mimimum collector limitation Adjustment range OFF / ON Factory setting OFF

The minimum collector temperature is a minimum switching temperature, which must be exceeded so that the solar pump (R1/R2) is switched-on. The minimum temperature shall avoid a steady starting-up of the solar pump (or solid fuel boiler charging pumps) for low collector temperatures. If the minimum temperature is underrun, in the display is shown (ﬂashing).

3.1.12 Option antifreeze function

OCF:

Antifreeze function Adjustment range OFF / ON Factory setting OFF

The antifreeze function activates the loading circuit between collector and tank if the adjusted antifreeze function is underrun in order to protect the medium that it will not freeze or „get thick“. If the adjusted antifreeze temperature is exceeded by 2 °F, the loading circuit will be deactivated.

Please note: As there is only a limited heat quantity of the tank available for this function, the antifreeze function should only be used in regions with few days of temperatures around freezing point.

CMN: Minimum collector temperature Adjustment range 14 ... 32 °F Factory setting 50 °F

CFR: Antifreeze temperature Adjustment range 14 ... 50 °F Factory setting 40 °F

3.1.14 Tube collector special function

If the controller measures an increase of 4 °Ra compared to the collector temperature tankd at last, the solar pump is switched-on to 100 % for about 30 seconds. After expiration of the solar pump runtime the current collector temperature is tankd as new reference value. If the measured temperature (new reference value) is again exceeded by 4 °Ra, the solar pump again switches-on for 30 seconds. If the switch-on difference between collector and tank is again exceeded during runtime of the solar pump or the standstil of the system, the controller automatically switches over to solar charging. If the collector temperature drops by 4 °Ra during standstill, the switch-on value for the special tube collector function will be recalculated.

O TC: Tube collector special function Adjustment range: OFF ... ON Factory setting: OFF

3.1.13 Recooling function

If the adjustem maximum tank temperature (S MX) is reached, the solar pump remains activated in order to avoid an overheating of the colle c t o r. The tank temperature might continue to increase but only up to 203 °F (emergency shutdown of the tank). In the evening the solar system continues running until the tank is cooled down to the adjusted maximum tank temperature via collector and pipes.

OREC: option recooling adjustment range OFF ... ON Factory setting: OFF

For control and service work the operating mode of the controller can be manually adjusted by selecting the adjustment value HAND, in which the following adjustments can be made:
