Mon – Fri 6:00 ... 3:00pm Comfort, otherwise Economy
Sat – Sun permanently Economy
Regulation according to internal sensor (switching the temperature sensor is performed with
●
a switch on the back of the regulator, see below)
Economy temperature 15 C, Comfort temperature 19 C
●
Range of entered temperature 5 °C - 30 °C, absolute
●
●
Hysteresis for control 1 K
●
Presence: remote controlled, with no option of editing
●
Display of values: current time, measured temperature
The temperature correction resets when the time program transitions into a different mode
●
DO2 offset (default 0) - temperature shift of the second stage from the first stage
●
(hysteresis is the same for both stages)
hysteresis 1K, DO2 offset 0K, required temperature 19 °C, DO1 (first heating stage) switches on
when temperature drops below 18 °C and switches off when the temperature reaches 19 °C, DO2
(second heating stage) switches on when temperature drops below 17 °C and switches off when
temperature reaches 18 °C. UC301 regulator communicates with the superior system with bus
RS485 in protocol Modbus RTU and can therefore be used in various control and monitoring
systems. For description of protocol see separate document, Controls, Modules and Regulators,
IRC, Communication Description.
