Maintenance and Service Life:
Warmhaus room thermostat should not come
into contact with water or excessive humidity. Unless an external damage
occurs, the room thermostat does not require any maintenance.
2.2.7. Use of Outside Temperature Sensor (Optional)
Outside Weather Temperature Sensor (optional) can be installed in your
combi by our Authorized Service (see: Installation Section; Accessory
Connection Scheme), and you can enable automatic temperature adjustment
for the radiator with immediate responses to outside weather temperature
changes via smart and comfort operation. Therefore, it maintains an efficient
and economic operation by reducing the radiator water temperature when
outside weather temperature increases and gradually increasing the radiator
water temperature when outside weather temperature decreases and sets
you free from making radiator temperature adjustments. This sensor is
activated when connected independently from the typology or availability
of used thermostat, the relation between output temperature and outside
temperature is defined according to curves given in the graphic below based
on position of button located on the combi panel.
After connecting the Outside Sensor, adjustment is made according to
average external weather temperature of your province with P04 parameter.
Our authorized service will make this adjustment during installation.
2.2.8. Customizing Combi Features
As your combi has an advanced electronic card, operation conditions and
certain parameters related with your preferences may be changed by our
Authorized Service. Please consult our authorized service when any changes
requested in below given parameters.
(P07) Controlled Power Increase Period.
When combi starts, it uses a controlled period defined for reaching the
adjusted maximum heating power. This period is adjusted as 3 minutes as
standard and can be increased up to 3 minutes.
(P08) Radiator (Heating) Power.
with actual heat requirement of installation place. Thus, the combi
automatically operates with variable gas flow rates depending on heat load
of installation between the minimum and maximum power.
(P21) Lowe temperature region selection.
This parameter should be adjusted as 1 for ground heating or heating systems
operating with low temperature. 0 (zero) value is selected for radiator
systems to operate at high temperatures as standard.
(P24) Child Protection
This parameter is not active as standard, please consult our Authorized
Service for activating the parameter (Protection lock is activated when
parameter is adjusted as 1). Buttons are locked after 2 minutes following use
of buttons when the function is active. Keylock is opened when the MODE
button is hold until cycle is completed for getting off the child protection.
Your combi is under control against setting changes upon activation of this
feature.
(P40) Radiator ignition delay period.
Combi device is equipped with an electronic timer for preventing frequent
ignition by the combi during heating stage. This period is adjusted as 2
minutes as standard and can be increased up to 10 minutes.
(P42) Ready Hot Water (Pre-Heating passive/active).
In order to rapidly prepare without waiting for your hot tap water request
and reducing the cold water consumption during waiting, grid water is
heated in the plate exchanger and ready hot water is stored. This function is
displayed on 6 buttons PriwaPlus LCD Screen.
Activation of this function in PRIWA PLUS, PRIWA ErP PLUS and ENERWA
models is performed with parametric adjustment by our Authorized Service
depending on your request.
Air Deareation Function
It is possible to activated deaeration function pressing RESET and (–) button
for circle time.
The "Air" will be displayed on the screen. Boiler will start the Air Deareation
function.
During this function pump and 3-way valve are activated/deactivated in
order to have deaeration of the hydraulic plant.
This function ends pushing again RESET and (–) button for circle time or at
the end of deaeration time: 12 minutes.
