2359Z61 Mounting without base Connection / power supply The room unit is powered by three 1.5 V Alkali batteries type AA (LR06). Radio connection Make the radio connection in the vicinity of the radio module prior to mounting so that all system are within easy reach. Prerequisite for the radio connection is that all components receive power, which means that the radio module must be correctly connected to the basic unit and the batteries must be correctly installed in the room unit.
Example of a display during the test: The digits on the left shows telegrams that have been sent, the digits on the right telegrams that have been received. The test will be ended after 24 telegrams. The test is considered successful when at least 50 % of the telegrams sent have been received. 2359Z140 Operator section Testmode If the test was not successful, some other mounting location is to be selected or the AVS14.390 radio repeater can be used.

Possible displays Depending on the type of unit, configuration and operating state, some of the info lines listed below may not appear.
Press the info button to switch to info display “Manual mode“, where the setpoint can be adjusted. Chimney sweep function SLT test The chimney sweep function is activated by a short press (maximum 3 seconds) on the chimney sweep button. This function produces the operating state required to make emission measurements (flue gas). The SLT test (SLT = safety limit thermostat) is activated by a long press (longer than 3 seconds) on the chimney sweep button.
5.1.2 Programming Setting principle Settings that cannot be made directly with the operating elements are made in the form of programming. For this purpose, the individual settings are structured in the form of operating pages and operating lines, thus forming practical groups of settings. The following example shows how to set the time of day and the date.

Thus, the frost protection setpoint of the room temperature is maintained. Comfort setpoint maximum The room temperature can be shifted according to different setpoints.
Heating curve displacement Heating curve adaption Parallel displacement of the heating curve is used to change the flow temperature evenly across the entire outside temperature range or, in other words, if the room temperature is always too high or too low, a readjustment must be made with the help of the parallel displacement. Adaptation of the heating curve is used by the controller to automatically adapt the heating curve to the prevailing conditions.
24-hour heating limit The 24-hour heating limit is used to switch the heating on and off in the course of the day, depending on the outside temperature. This function is used primarily during intermediate seasons (spring and fall) to respond to short-time temperature variations. Example: Setting line e.g.
Setting Type of compensation − − −% 1…99 % Pure weather compensation * Weather compensation with room influence * Pure room compensation 100 % * Outside sensor required. Pure weather compensation The flow temperature is calculated via the heating curve, depending on the composite outside temperature. This type of compensation calls for a correct adjustment of the heating curve since in that case the control gives no consideration to the room temperature.

DHW storage tank During solar charging, preference is given to the DHW storage tank. At every level A, B or C (see below), it is charged with priority. Only then will the other consumers of the same level be charged. As soon as all setpoints of a level are attained, those of the next level are approached, whereby priority is again given to the DHW storage tank. Buffer storage tank During solar charging, preference is given to the buffer storage tank.

Increase of transfer boost Heat transfer makes it possible to transport energy from the buffer storage tank to the DHW storage tank.
5062 El immersion heater control External thermostat DHW sensor Electric immersion heater operating mode Substitute The electric immersion heater is only used if the boiler delivers a fault status message or has been shut down via boiler lock. This means that in normal situations the DHW is always heated by the boiler. Summer The electric immersion heater is used as soon as all connected heating circuits have switched to summer operation.

• OFF: The separate circuit is switched off. Every boiler in use can charge the DHW storage tank • ON: The separate circuit is switched on.

EX2 FX4 (T6) QX4 (T7) QX4 (T8) Modulating 3-position Modulating UX Use Space Input 1st burner stage hours run Phase 2nd burner stage Z Connector type AGP8S.04C/109 2nd burner stage off 2nd burner stage on Boiler temperature control The functioning and activation and deactivation of the first stage corresponds to that of 2-stage burner operation. Release of modulation is analogous to the release of burner stage 2.
Burner control • 3-position control and modulating UX The actuator is controlled in PID mode. By setting the proportional band (Xp), the integral action time (Tn) and the derivative action time (Tv), the controller can be matched to the type of plant (controlled system). Also, the actuator running time is to be set. • Neutral zone For control operation, a neutral zone is used which is at +/- 1K about the current boiler temperature setpoint.
2 x 1 cascade The 2x1 cascade is a special configuration of the basic unit, where the 2-stage boiler is operated as 2 cascaded 1-stage boilers. Due to the temperature differential between boiler temperature setpoint and boiler temperature sensor B2 (common, mandatory cascade flow temperature sensor), switching on / off of the lag boiler (release and reset integral) takes place according to the control of a 2-stage burner. The same parameters are used.
When using a diverting valve, it is always only one heat exchanger that can be used at a time. Only alternative operation is possible. When using a charging pump, all heat exchangers can be used at the same time. Either parallel or alternative operation is possible. External solar exchanger In the case of solar plants with 2 storage tanks, it must be selected whether the external heat exchanger shall be used jointly for DHW and as a buffer storage tank, or exclusively for one of the two.
Collector pump Q5 When using a solar collector, a circulating pump for the collector circuit is required. Pump H1 Q15 Pump H1 can be used for an additional consumer. Together with an external request for heat at input H1, it is possible to operate an air heater or similar. Boiler pump Q1 The connected pump is used for circulating the boiler water. Bypass pump Q12 The pump connected serves as a boiler bypass pump for maintaining the boiler return temperature.
Heat gen shutoff valve Y4 If the buffer storage tank holds a sufficient amount of heat, the consumers can draw their heat from it, and the heat sources need not be put into operation. Automatic heat generation lock locks the heat sources and hydraulically disconnects them from the rest of the plant with the help of heat source shutoff valve Y4. This means that the heat consumers draw their energy from the buffer storage tank and wrong circulation through the heat sources will be eliminated.
St tank transfer pump Q11 If the temperature level of the buffer storage tank is high enough, the DHW storage tank can be charged by the buffer. This transfer can be made by means of transfer pump Q11. DHW mixing pump Q35 Separate pump for storage tank circulation during the time the legionella function is active. DHW interm circ pump Q33 Charging pump with DHW storage tank using an external heat exchanger. Heat request K27 As soon as there is demand for heat, output K27 is activated.

• Central effect (LPB) When using LPB device address = 1, excessive heat dissipation also acts on the consumers connected to the other controllers in the same segment. The distribution of excessive heat from segment 0 across other segments of the system is not possible. Temperature value Heat generation receives heat requests in the form of voltage signals (DC 0...10V). The associated setpoint is to be adjusted on operating line 5954.
