FUNCTIONS The Riello Programmable 7-day Thermostat has the following functions: Room thermostat (crt): for the display appearance in this mode, please refer to the relevant section of this manual. The internal temperature sensor detects the temperature and, comparing with the set point, switches ON or OFF the heating request (according the programmed timing). The temperature sensor is located on the left side of the item. Temperatures: there are two level of selectable temperature: Comfort temperature T1 and economy temperature T2 (T1 always > T2). Both are selectable. Additionally there is a third level of temperature indicated as frost protection temperature that is active all the time (the frost protection temperature is selectable only inside the technical menu). 8
T2 always > Frost protection temperature) Time: on the display it is possible to set and read the time (24 hours display mode) Day: on the display it is possible to set and read the day of the week Programming timing: it is possible by selecting the relative timing fascia to select the desired time. The programming is possible during 7 day 24-hours and the minimum time fascia is 30 minutes. The programming is possible in two separated temperatures: COMFORT (T1 ) and ECONOMY (T2 ). Status mode in crt: select the heating mode button for fast switching between the 4 status OFF AUTO PARTY - HOLIDAY. OFF mode, the heating request to the boiler is off, on display there is not equivalent icon, the heating layer and the programming fascia is off. With this mode only the frost protection function is active. AUTO mode: the heating request is according the programmed timing and room temperature. In AUTO mode it is possible to increase or decrease temporary the room set temperature by pressing the and buttons, only if the current time is inside in a heating ON fascia. The temporary new temperature set (T1) is maintained only inside the timing fascia. The next heating fascia will be back to the original T1 set temperature. It is possible to check the set temperature by pressing once the 9
or the buttons only if the current time is inside in a heating ON fascia. HOLIDAY mode with choice how many day off (by increasing or decreasing using the button and ). The heating request to the boiler is to maintain the economy temperature on the room (T2). The number of days off is considered on the day starting from midnight. After the counter down is ended the programmer switch to AUTO mode. PARTY mode automatically switch the programmer ON to comfort temperature (T1). This status is forced up to midnight, after, the programmer goes back to the programmed timing fascia. Remote Control (): for the display appearance in this mode, please refer to the relevant section of this manual. The internal temperature sensor detects the temperature and, comparing with the set point, calculates the most suitable boiler flow temperature according the climatic curve (only if the external sensor is fitted) and according the velocity the set temperature is reached. The programmer continuously communicates with the boiler control indicating the target flow temperature (the values not just an ON/OFF) according to the calculation made. With this type of communication it is possible also to adjust by remote the domestic hot water (DHW) temperature in case of instantaneous DHW production or DHW storage tank controlled by a dedicated sensor. The functions of this type () are the same as room thermostat type above 10
described. Additionally it is possible to have a feedback from boiler status and alarms. The display in type give more information according the already mentioned start up indications.
