Värmebaronen EK 15E
Alternative temperature with room unit
Upon activation, the centre point of the setpoint adjuster
is moved by the set number of stages.
For example, the centre position of the handwheel is 20-6 =
14°C if the alternative temperature parameter is set to -6.
Optional Room Unit
The control can be equipped with a room unit with a setpoint
adjuster, handwheel and an alarm indicator, which has the
same function as the red indicator on the front panel.
The room unit increases heating comfort with the lowest
possible energy consumption. Additional information is
included with the device.
Further information is provided with the room unit.
The room unit requires that the UTK function is activated.
Room unit; "User level" rows 10 and 11 and "Service level"
row 8.
Over temperature protection
The overtemperature protection supplements
the overheating protection. The aim is to prevent the
overheating protection from triggering as far as possible.
The temperature at which over-temperature protection
is tripped can be set as a fixed value or in relation to the
setpoint. See "Advanced Service level" rows 16 and 17.
Safety valve
To maintain the safety function, safety valves in the heating
system must be operated regularly, about 4 times a year.
Venting - water pressure
Regularly check that the water pressure is correct.
Air may be left in the system for a while after installation,
for which reason it should be vented a few more times.
The pressure in a heating system varies with the
temperature. Do not add water unnecessarily!
Draining
If the heating system needs to be drained of water,
the electric flow heater must first be switched off
so that the immersion heater is not damaged.
Operation and maintenance
Overheating protection
The electric flow heater's overheating protection is triggered
if the temperature exceeds approximately 100°C. Protection
is reset when the "reset plug" on the front panel is removed.
Reset can only be done when the temperature has fallen
below 80°C.
Always check the cause of a guard being
triggered! If the protection is triggered
repeatedly, the cause must be fixed!
Action in the event of a risk of freezing
When it is extremely cold, no part of the heating system
must be switched off as there is a risk of bursting.
If you suspect that any part of the heating system is frozen,
contact an installation engineer.
If the heating system is to be switched off for an extended
period of time, the system should be drained or it can
be filled with water mixed with glycol.
The electric flow heater must not be operated
if you suspect that any part of the heating
system is frozen.
Call an installation engineer!
Frost protection - heating systems
If the heating system's water is mixed with glycol,
it is important to check that the glycol contains a suitable
quantity of corrosion-protection additive. When glycol
breaks down, one of the by-products is carbonic acid,
which increases the risk of corrosion.
Frost protection
The ECO function activates the frost protection automatically
when the boiler temperature is below 10°C. See "User level"
row 12.
