Operating Status; Summer Mode - Riello RESIDENCE KIS Series Installer And User Manual

Offset on the reference ambient temperature (fig. 20)
The user can, in any event, indirectly intervene on the value of the HEATING
setpoint setting, with reference to the reference temperature (20°C), an
offset within the range -5 - +5 (offset 0 = 20°C).
For correcting the offset see the paragraph "4.9 Adjusting the heating water
temperature with an outdoor temperature sensor connected".
NIGHT COMPENSATION (parameter NIGHT COMP - fig. 20)
If a ROOM THERMOSTAT is connected to a programming timer, from the
menu CH parameter NIGHT COMP the night compensation can be enabled.
To set the night compensation:
ƒ access the technical parameters menu, as indicated in the paragraph
"3.21 Access to the parameters"
ƒ select the menu CH and then NIGHT COMP
ƒ press the key to confirm
ƒ set the parameter to 1
Enter
ƒ confirm with
In this case, when the CONTACT is CLOSED, the heat request is made
by the flow sensor, on the basis of the outdoor temperature, to obtain a
nominal ambient temperature on DAY level (20°C).
The opening of the contact does not produce a switch-off, but a reduction
(parallel translation) of the climatic curve on NIGHT level (16°C).
Also in this case, the user can indirectly modify the value of the HEATING
setpoint inserting once again an offset on the reference DAY temperature
(20°C) rather than NIGHT (16°C) that can vary within the range [-5 - +5].
For correcting the offset see the paragraph "4.9 Adjusting the heating water
temperature with an outdoor temperature sensor connected".
4.6 First commissioning
ƒ Position the system's master switch to the "on" position.
ƒ Open the gas tap to allow fuel to flow.
ƒ With power on the backlight comes on, then all the icons and the segments
come on for 1sec and in sequence the firmware revision is displayed for
3sec:
ƒ Then the interface displays the status active at that moment.
Vent cycle
b
Each time that the boiler is powered, an automatic vent cycle is
carried out lasting 4 min. When the air purging cycle is in progress all
heat requests are inhibited except those for domestic hot water when
the boiler is not set to OFF and a scrolling message is displayed on
the interface screen "AIR PURGING CYCLE IN PROGRESS".
The purge cycle can be interrupted early by keeping key 2 pressed for at
least 2 seconds (the icon RESET comes on).
The purge cycle can also be interrupted, if the boiler is not set to OFF, by a
domestic hot water request.
ƒ Adjust the ambient temperature thermostat to the desired temperature
(~20°C) or, if the system is equipped with a programmable thermostat
or timer, ensure that the thermostat or timer is "active" and set correctly
(~20°C).
ƒ Then set the boiler on WINTER or SUMMER depending on the type of
operation desired.
ƒ The boiler will start up and continue working until the set temperatures
are reached, after which it will then go back to standby.

Operating status

For changing the operating status from WINTER to SUMMER to OFF press
key 1 until the icon for the desired function is displayed.
WINTER MODE
ƒ Set the boiler to the WINTER status by pressing key 1 until both the
domestic hot water icon and the heating icon are displayed.
The interface normally displays the delivery temperature unless there is
a domestic hot water request in progress, in which case the domestic hot
water temperature is displayed.
ƒ When there is a heat request and the boiler is igniting, the icon "
appears on the display.
Heating REQUEST, the radiator icon blinks:

SUMMER MODE

ƒ Set the boiler to the SUMMER status by pressing key 1 until the domestic
hot water icon is displayed.
In this status the boiler activates the traditional function of just domestic hot
water, the interface normally displays the delivery temperature.
In the event of a domestic hot water pick up, the display shows the
temperature of the domestic hot water.
