Block heat pump based on external temperature and/or parameter
If the external temperature is too low, heat pump performance will not be acceptable; hence, you can:
•
Block the heat pump from parameter tr16:
•
Set a set point (tr17) below which the heat pump will be disabled.
When the heat pump is blocked, the setpoint differentials for heaters in integrated use and boiler will be forced to zero.

Block heat pump from digital input
If a digital input is configured as “Block heat pump” CF16..CF20 / CF23..CF26=32 when it is activated, the heat pump will be deactivated.
When the heat pump is blocked, the setpoint differentials for heaters in integrated use and boiler will be forced to zero.
Economy function
The parameters for this function are as follows:
tr19 Setpoint differential in Cool from start of Economy
tr20 Setpoint differential in Heat from start of Economy
In UST500, a digital input (DI1…DI5 or AI1…AI4 configured as digital inputs)) can be configured as Economy Input (CF16..C20,
CF23…CF26=+26/-26)
If a digital input configured as Economy is active*, an offset is added to the operating setpoint (positive or negative). See the table below:

**The cool and heat setpoints represent the real operating setpoints (i.e. those set in parameters tr04 and tr05 respectively), including any
function decalibration enabled (such as the dynamic setpoint for example).
