H outdoor temperature sensor H boiler water temperature sensor H DHW tank temperature sensor H Power/Pump Module

For the heating circuit with a mixing valve, a mixing valve actuator accessory kit is required. Due to the low return water temperature of condensing boilers only 3-way mixing valves should be installed. The circulation pump with a flow check valve for DHW tank temperature control must be ordered separately.

Heating system with underfloor heating The underfloor heating circuit requires an accessory kit for operation with a mixing valve. A temperature control with high limit must be installed in the heating supply of the radiant floor heating application. The underfloor heating circuit must not be controlled by a remote control with room temperature sensor.

Structure and Operation

Modular structure

The complete control consists of a control base, control unit (electronic/operating modules) and a Power/Pump Module. The control unit comprises: Power on/off switch, an electronic high limit, a temperature gage and a low temperature control adjustable high limit fixed high limit TUV test switch, override switch, buttons for: holiday program party and economy modes reduced operating mode temperature domestic hot water temperature programming of heating curves for boiler water temperature and/or mixing valve circuit temperature

heating circuit selection, a selector knob for normal operating temperatures and a digital timer. Heat-demand-controlled circuit pump and burner activation, adjusting of a variable temperature limit, pump cycling, integrated diagnostic system and flue gas monitoring in connection with flue gas temperature sensor (optional) and maintenance display.

Boiler-specific functions

The Vitotronic control modulates the boiler water temperature. It gradually regulates the boiler water temperature (= the supply temperature of the direct-connected heating circuit) as well as the supply water temperature of a mixing valve circuit. The control contains an adaptive tank temperature control logic with priority switching (heat pump off, mixing valve closed). An additional function for domestic hot water heating (short-term heating to an increased temperature) can be selected.

The Vitotronic 200 is an ideal control option for your heating system with mixing valve circuit. It is the perfect solution for your underfloor heating circuit with supply and return water temperature sensor or for controlled drying of a concrete floor.

Structure and Operation (continued)

Digital timer of operating unit

A digital timer with day and week feature, calendar, automatic resetting to daylight savings time and automatic functions for domestic hot water heating and recirculation pump. Time, day and standard switching times for room heating, domestic hot water heating and domestic hot water recirculation pump are factory preset (individually programmable), max. four time switch intervals programmmable per day. Shortest interval: 10 minutes Power reserve: 5 years

Adjusting the operating system

All operating programs feature freeze-up protection*1 for the heating system. With the program selector buttons the following can be selected: heating and domestic hot water domestic hot water only standby operation

*1 See Freeze-up Protection Function below.

Freeze-up protection function

The freeze-up protection function is activated when the outside temperature drops to +34 F/1C. The freeze-up protection function activates the circulation pumps and keeps the boiler water temperature at the reduced operation setpoint level, at a minimum temperature of approx. 68 F/20 C (for heating boilers with low limit the respective temperature will be maintained).

deactivated when the outside temperature exceeds +37 F/3 C. When the freeze-up protection function is deactivated, heating boiler and circulation pumps are turned off.

Summer economy mode

(Domestic hot water heating only, program selector switch )

The burner only activates if domestic hot water needs to be produced (as required by DHW setpoint).

Heating curve adjustment

The weather-responsive Vitotronic 200 regulates the boiler water temperature (= supply water temperature of the heating circuit without mixing valve) and the supply temperature of the heating circuit with a mixing valve. The required supply temperature for a certain room temperature depends on the heating system and the insulation of the building in question. The adjustment of both heating curves individually allows for the boiler water temperature and the supply temperature of the mixing valve circuit to be adjusted to the respective conditions.

Heating curves:

Low temperature heating system, e.g. radiant floor heating Medium temperature heating system, e.g. cast iron radiation, staple-up radiant floor heating High temperature heating system, e.g. fintube radiation, fan coils

The maximum boiler water temperature is restricted by both the adjustable high limit and the electronic maximum temperature limit. The supply water temperature cannot exceed the boiler water temperature.

Note on the room temperature sensing function (RS function)*1 when using a remote control

Due to the slow response of the underfloor heating, the RS function must not influence the underfloor heating circuit. For heating boilers with a low limit, the RS function must not influence the heating circuit without a mixing valve.

*1RS function = remote control with room sensor function

*2WS function = remote control only, no room sensor function
