What are the assumptions behind the different Control Strategies - Get heat / Timer / Prevent heat / sun etc. Pls explain so I understand what the simulation does.

Pls. see the following extract from the user manual:

Sun The shading will be drawn when the solar irradiance on the unshaded window exceeds 100 W/m2.

Sun + Timer The shading will be drawn when the solar irradiance on the unshaded window exceeds 100 W/m2 and also between 22 PM and 7 AM.

Sun + Get heat The shading will be drawn when the solar irradiance on the unshaded window exceeds 100 W/m2 during time when people are present in the room. During time of no presence, the shading will be activated when the irradiance is above 100 W/m2 only if the room does not need heating.

Sun + Get heat + Preserve heat The shading will be drawn in the same way as for Sun + Get heat, but also during the night time when there is a heating demand and the room has no presence of people.

Always drawn Shades are permanently in down position

Never drawn Shades are up

Schedule Shades are drawn according to user-specified schedule
