In this menu, all adjustments for the heating circuit can be made. Additionally, the screed drying function can be activated and adjusted.

6.1 Shared relays

In this menu, 1 shared relay can be activated and adjusted. Further options such as a minimum and a maximum limitation for boiler protection are also available. The shared relay will be available for selection under Virtual in the relay allocation channel of the Heating circuit menu.

Note:

Activate and adjust the shared relay rst. It will then be available in the

Demand

For demand of a boiler, for example, the shared relay Demand 1 is available. The options Boiler protection min and Boiler protection max can be activated for the shared relay, allowing temperature-dependent control of the boiler demand. For this purpose, a boiler sensor is required.

The Boiler pr. min option is used for protecting an older type boiler against cool- ing. If the temperature falls below the adjusted minimum temperature, the allocated relay is energised until the minimum temperature is exceeded by 2 K.

The Boiler pr. max option is used for protecting an older type boiler against overheating. If the adjusted maximum temperature is exceeded, the allocated relay is switched off until the temperature falls by 2 K below the maximum temperature.

6.2 Heating circuit

The controller has one heating circuit. The following heating circuit variants are possible:

• 1 mixed weather-compensated heating circuit

• 1 unmixed weather-compensated heating circuit

• 1 mixed constant heating circuit

The heating system Constant is only available in a mixed heating circuit. An outdoor temperature sensor cannot be allocated.

Heating system Constant:

Set ow temperature = set temperature + remote control + day correction or

night correction

Heating system Curve:

Set ow temperature = heating curve temperature + remote control + day correction or night correction

The calculated set ow temperature is limited by the adjusted values of the parameters setowtemperature and owminimumtemperature.

Flow maximum temperature ≥ set ow temperature ≥ ow minimum temperature

If the measured ow temperature deviates from the set ow temperature, the mixer will be activated in order to adjust the ow temperature correspondingly.

The mixer runtime can be adjusted with the parameter Interval. The parameter Pump off is used for switching off the heating circuit pump, if the

adjusted value of the ow maximum temperature is exceeded by 5 K.

Installation

CommissioningSettingsTroubleshooting

The heating system Constant aims to keep the set ow temperature to a constant value which can be adjusted by means of the parameter Set temperature.

If the heating system Curve is selected, the controller calculates a set ow temper- ature by means of the outdoor temperature and the selected Heating curve. In both cases, the dial setting of the remote control and the controller day correction or night correction are added.

If the outdoor temperature sensor is defective, an error message will be indicated.

For the duration of this condition, the maximum ow temperature -5 K is assumed as the set ow temperature.

The Remote control allows manual adjustment of the heating curve (± 15 K). Fur- thermore, the heating circuit can be switched off or a rapid heating can be carried out by means of the remote control.

Heating circuit switched off means that the heating circuit pump is switched off and

the mixer closed. The ow temperature is boosted to maximum for rapid heating

when the remote control is set to rapid heating.

Outdoor temperature in °C

The automatic summer mode becomes active when the outdoor temperature exceeds the adjusted summer temperature TSummer. This can be limited to a daytime frame with the parameters Daytime on and Daytime off. Outside the adjusted time frame, the lower temperature TNight is used in summer mode. In summer mode, the heating circuit is switched off.

With the Timer, the day / night operation can be adjusted. During day phases, the set ow temperature is increased by the adjusted Day correction value, during night phases it is decreased by the Night correction value (night setback).

The parameter Mode is used for selecting between the following correction modes: Day / night: A reduced set ow temperature (night correction) is used during night

operation. Day / off: The heating circuit and the optionally activated afterheating are switched

off during night operation. Room / off: The heating circuit and the afterheating are switched off during night

operation. If the temperature falls below the adjusted limit temperature at the allocated room sensor, the controller changes to the reduced heating mode.

Outdoor / Off: The heating circuit and the afterheating are switched off during night operation. If the temperature falls below the adjusted limit temperature at the allocated outdoor temperature sensor, the controller changes to the reduced heating mode.

The Timer HC can be used for adjusting the time frames for day operation (see page 23).

Installation

For heating circuit afterheating, the calculated set ow temperature is compared

with the temperature at one reference sensor. If the temperature difference falls below the switch-on value DTo n , afterheating will be activated. If the temperature difference exceeds the switch-off value DToff, afterheating will be switched off.

If Thermostat is selected, the set ow temperature is compared with a store reference sensor. If Zone is selected, the set ow temperature is compared with 2 reference sensors. The switching conditions at both reference sensors have to be

fullled.

If the system has a store, the Starting time can be used for activating the afterheating before the day operation in order to heat the store to a sufciently high temperature.

With the Room thermostat option, one single room can be integrated into the control logic.

A sensor input can be allocated to the room thermostat. The temperature at the allocated sensor is monitored. If the measured temperature exceeds the adjusted value TambSet and if the parameter HC off is activated, the heating circuit will switch off.

Common room thermostats with potential-free outputs can be used alternatively. In this case, Switch must be selected in the Type channel. The input S4 must pre- viously be set to Switch in the Inputs / Outputs menu.

When the Timer option is activated, a timer is indicated in which time frames for the function can be adjusted. During these time frames, the adjusted room temperature decreases by the Correction value.

Note: For information on timer adjustment see page 9.

An additional relay can be allocated to the room thermostat. That relay will switch on when the temperature falls below the adjusted room temperature. This way, the room in question can be excluded from the heating circuit via a valve as long as the desired room temperature is reached.

In the channel RTH , the room thermostat can be temporarily deactivated or re-activated respectively. All adjustments remain stored.

Antifreeze function

The antifreeze function of the heating circuit can be used to temporarily activate a heating circuit during sudden temperature drop in order to protect it against frost damage.

The temperature at the ow sensor is monitored. If the temperature falls below the

adjusted antifreeze temperature TFrost, the heating circuit will be activated until the antifreeze temperature is exceeded by 2 K, but at least for 30 min.

Chimney sweeper function

The chimney sweeper function can be used for enabling quick access to measurement conditions without having to navigate through the menu.

The chimney sweeper funtion is activated by default. The chimney sweeper mode can be activated by pressing microbutton ♦ for 3 s.

In the chimney sweeper mode, the heating circuit mixer opens, the heating circuit pump and the afterheating contact are activated. If the chimney sweeper function is active, the Lightwheel

ashes yellow. Additionally, Chimney sweeper and a

countdown of 30 min are indicated on the display. When the countdown has elapsed, the chimney sweeper mode is automatically de-

activated. If, during the countdown, microbutton ♦ is again pressed for more than 3 s, the chimney sweeper mode will end.

accessories

AM1 Alarm Module

The AM1 Alarm Module is designed to signal system failures. It is to be connected to

the VBus

of the controller and issues an optical signal via the red LED if a failure has occurred. The AM1 also has a relay output, which can e. g. be connected to a building management system (BMS). Thus, a collective error message can be issued in the case of a system failure. Depending on the controller and the sensors connected, different fault conditions can be signalled, e. g. sensor failures, excess or negative

system pressure as well as errors in the ow rate, such as a dry run of the pump.

KM1 Communication module

The KM1 Communication module is the network connection for solar and heating systems, especially suited for technicians managing large systems, heating installers and home owners who like to keep a close eye on their system. The system can be parameterised over the Internet. VBus.net enables e. g. controlling the system yield in a comprehensive system scheme image.
