SMART HDO MODE

The thermostat monitors the signal HDO and saves its weekly history. SMART HDO
mode operates identical to SMART with the extension; based on saved history of HDO it
assumes the high tariff periods when heating is not possible. It starts automatically
heating the boiler in advance in order to have available required amount of hot water
for the user consumption as recorded in the history of SMART mode consumptions.
During high tariff, the switching of the heating spiral is blocked.
3.1.3

MANUAL MODE

Common thermostat mode. The controller keeps the heater at constant, user defined
temperature in the range between 40 to 80°C. A standard thermostat function - keeps
the heater constantly warmed up to the set temperature.
3.1.4

MANUAL HDO MODE

When low price electricity tariff is detected, the controller keeps the heater at constant,
user defined temperature, identically to MANUAL mode. During high tariff, the control
of the heating spiral is blocked.
3.1.5

OPTIMUM IN MODE MANUAL AND MANUAL HDO

Recommended temperature for manual setting (55°C). During this temperature, the
best efficiency of smart heater is achieved.
3.1.6

PROG MODE

The mode is similar to MANUAL mode providing two temperatures are set to which the
thermostat reacts. The switching between the temperatures is provided based on the
weekly programmer program. Time differentiation of the weekly programmer is 1 hour.
The weekly programmer configuration is performed by means of the control application
Android or iOS.
If power failure occurs resulting in the loss of real time data, PROG mode cannot operate
according to the set program until the user resets the correct time. In this case the
heater temperature is regulated to higher temperature set for the mode PROG.
3.1.7

ANTI-FREEZE MODE

The mode of putting the heater out of operation (holiday programme). Makes sure that
the temperature of water in the heater does not drop below 5°C (electricity supply is
necessary). This function is functional in all mode, including active HDO and high tariff.
This sign includes green light on with active HDO receiver.
