Winter and summer compensation of relative humidity setpoint

Remote control point adjustment

The calculated room humidity setpoint can be changed (-...0...+) by the remote control point adjustment input "RelHumSpAdj". To define these plus/ minus values, a wall module macro should be applied for connecting the input "RelHumSpAdj".


Winter and summer compensation

The calculated room humidity setpoint is outside air compensated, defined by parameters WC-01, WC-02, SC-01 and SC-02, and limited between minimum and maximum values, defined by parameters RAH-01 and RAH-02, as shown in the next figure:



The winter compensation function prevents condensation on window screens, while the summer compensation function saves on cooling-load during the de-humidification process.
