CB - Control

This control VI does not contain any logic that provides operation set points for the condensing boiler. The tasks of this control VI is:

• Generate outlet signal to the condensing boiler for the mode, the boiler runs in (temperature or power setpoint)
  
• select the mode of the condensing boiler

Important: Before switching the input for the boiler control mode (temperature or power setpoint), the according parameter for the mode has to be cahnged manually at the boiler menu (directly at the hardware). See also SF1 Wolf CGB-2-14 and SF2 Wolf CGB-2-20.

Inputs:

• On/off signal for the boiler: on / off $//<![CDATA[ \begin{array}{l}[bool]\end{array} //]]>$ 
• Control_Strategy: by burner power (0) or by target boiler temperature (1) $//<![CDATA[ \begin{array}{l}[-]\end{array} //]]>$
• power setpoint for the condensing boiler (if Control_Strategy = 0): EB_power_kW $//<![CDATA[ \begin{array}{l}[kW]\end{array} //]]>$
• temperature setpoint for the condensing boiler (if Control_Strategy = 1): S_TM-CP_set $//<![CDATA[ \begin{array}{l}[^\circ C]\end{array} //]]>$

Outputs:

• Temperatures and flow rates as shown in CB - Hardware $//<![CDATA[ \begin{array}{l}[l/min]\end{array} //]]>$ and $//<![CDATA[ \begin{array}{l}[^\circ C]\end{array} //]]>$
• Thermal power $//<![CDATA[ \begin{array}{l}[kW]\end{array} //]]>$
• Thermal efficiency $//<![CDATA[ \begin{array}{l}[-]\end{array} //]]>$
