I have just set up the devices for ViCare Smart Climate and my radiators are still cold. Is this normal behavior?

ViCare Smart Climate Features

The ViCare app allows you to create schedules for heating and hot water based on your daily routines. If you already use ViCare and have now added a device to ViCare Smart Climate, e.g. radiator thermostat or climate sensor, these schedules can be preserved by copying them from a day of the week to a room. The ViCare Time Assistant also helps you to create or edit existing schedules.
