Basics Product description, Features, Functionality Product description The THISION S controller is a weather compensated digital controller that can control one mixed heating zone, one direct heating zone, DHW preparation and burner operation. Additional functions can be activated. The controller calculates the required temperatures for the boiler and the heating zones according to the outside temperature and controls DHWpreparation.
Basics When shipped from the factory, the heating controller is configured as follows: DHW heating active if a DHW sensor is connected Shifting heating circuit 1 4 Further combinations can be configured by setting the appropriate parameters and selecting auxiliary functions in the start-up menu.

Detailled settings Menu: time of day and date Menu: Operator section Time of day and date The controller has a yearly clock with time of day, weekday and date. To ensure the controller´s functionality, both the time of day and the date must be correctly set.
Menu: Operator interface Units The display can be switched between the SI units (°C, bar) and U.S. units (°F, psi). Heating circuit assignment Line no.
Menu: Time programs Menu: Holiday For the heating circuits and for DHW heating, a number of switching programs are available. They are activated in Automatic operation and control the change of the temperature levels (and the associated setpoints) via the selected switching times. Entering the switching times The switching times can be set in a combined way, that is, either jointly for several days or in the form of se¬parate times for individual days. When preselecting groups of days like for instance Mo..
Menu: Heating circuits For heating circuits, there are various functions available which can be individually set for each heating circuit. Room setpoint Room temperature The room temperature can be shifted according to different setpoints. These setpoints become active depending on the selected operating mode, thus producing different temperature levels in the rooms. The ranges of adjustable setpoints result from the interdependencies, as this is shown in the following diagram. Line no.
Menu: Heating circuits Heating curve slope As the heating curve slope is raised, the flow temperature increases quicker at lower outside temperature. In other words, if the room temperature is not correct at low outside temperatures but correct at higher outside temperatures, the heating curve slope requires readjustment. Increase adjustment: Raises the flow temperature, especially when outside temperatures are low.
Menu: Heating circuits ECO-Function Summer/winter heating limit The summer / winter heating limit is used to switch the heating on and off in the course of the year, depending on temperature conditions. In automatic mode, switching on / off takes place automatically, so there is not need for the user to do this manually. By changing the setting, the respective periods of time will be shortened or extended. Line no.
Menu: Heating circuits Flow temp setpoint min/ max Using this limitation, a temperature range for the flow temperature setpoint can be defined. If the flow temperature setpoint demanded by the heating circuit reaches the relevant limit and the heat request increases or decreases, the flow temperature setpoint will be maintained at the maximum or minimum limit. Line no.
Menu: Heating circuits Room temperature control and limitation With the room temperature limitation function, the heating circuit pump can be disabled if the room temperature exceeds the current room temperature setpoint by more than the preset differential. Line no. HC1 HC2 760 1060 Operating line Factory setting Room temp limitation P SDR t TRw TRx The room temperature limitation does not work in the case of pure weather compensation.
Menu: Heating circuits Optimum start / stop control Line no. HC1 HC2 Operating line Optimum start control max The change from one temperature level to the other is optimized in a way that the comfort setpoint is reached at the relevant switching time.
Menu: Heating circuits Mixing valve control Mixing valve boost To ensure proper mixing valve flow temperature control, the flow temperature must be higher than the demanded setpoint of the mixing valve flow temperature. The value set here is added to the request. The selection of the type of actuator determines the control behavior for the type of mixing valve actuator used. Line no.
Menu: Heating circuits Variable speed pump The pump in the THISION S for heating circuit 1 is speed controlled according to the hydraulic standard. Speed design point Sets the speed level (1-24) of the pump at the design point for achieving the nominal flow rate. If necessary, the fan speed can be reduced (hydraulic adjustment). This corresponds to the analogue speed selector switch on the pump. The "variable speed pump" function is active in hydraulic diagram 3 and 60, in line no. 5701. Line no.

Menu: DHW Setpoints The DHW setpoint acting on the control is selected based on the current operating level which includes impact of the operating mode, the release (possibly the switching program), the DHW push and the 0 legionella function. Line no. 1610 1612 Operating line Factory setting Nominal setpoint Reduced setpoint 55°C 40°C DHWN DHWmax DHWR DHWmax DHWN DHWR Release Line no.
Menu: DHW Legionella function Line no. Periodically The legionella function is repeated according to the interval set (operating line 1641). The legionella setpoint is attained via a solar plant, independent of the period of time set, the period of time will be newly started. This means that the heat source is switched on only if the solar plant could not deliver the required “Legionella function setpoint” within the adjusted period of time.
Menu: Boiler Heat generation lock With this parameter, the heat generation lock function is released. If this is the case, the burner and the boiler pump are turned off when, for example, due to a programmed input or a sensor of the clip-in AGU 2514, the burner is locked from the outside or the temperature at the sensor of the clip-in is high enough to supply the consumers. Setpoints The controlled boiler temperature setpoint can be limited with Setpoint min and -max.
Menu: Buffer storage tank General: The buffer storage tank function and menu are only active when in the configuration menu, line no 5973 is set as “Heat generation lock sensor”. Auto generation lock The automatic heat generation lock brings about a temporary hydraulic separation between heat source and buffer storage tank. The heat source is put into operation only when the buffer storage tank is no longer able to cover the current demand for heat.
Menu: Solar Line no. General: The solar function and the solar menu are only active when a solar Clip-In AGU 2.530 and collector sensor are connected to the LMU. In addition, in the configuration menu, in parameter 5978, the function input SolCl is set to collector sensor.
Menu: DHW storage tank Charging Flow setpoint boost The DHW request to the boiler is made up of the current DHW setpoint plus the adjustable charging boost. Recooling collector With solar function activated, excess energy from the drinking water tank when the collector is cold (at night) is routed to the environment via the collector.

If the parameter is set to 0 there is no pump shutdown. In addition, working with the delay in parameter 5733 must be set to 0 seconds. Line no.

Menu: Configuration Line no. Function input H1 (programmable input) On the LMU programmable input the following functions can be selected, that are activated by an external contact. Function input RelCl On the programmable input of the clip-in (not the solar Clip-In), the following functions can be selected, which can be activated by an external contact (function 0,1,2,3,7,8,9,), an analogue signal (function 4,5) or via a sensor (function 6,11).

Operating line 6705 SW Diagnostic code 6741 Time before alarm HC2 Factory setting --240 min. SW Diagnostic code An internal software error currently pending in the system is displayed here with diagnostic code indicating where the error occurred.
Menu: Service/special operation Chimney sweep function The burner is started up. To ensure that burner operation will be as continuous as possible, only maximum limitation of the boiler temperature is active to be used as the switch off point. To reach the minimum boiler temperature of 60 °C as quickly as possible, all consumers are locked for that period of time by an absolute locking signal. Line no.
