Operation
Displaying the water pressure
On the RoCon mb control unit, the system pressure (water
pressure) of the internal circuit (direct heating circuit) can be dis-
played when it is switched on. The water pressure is the first info
parameter available after the operating data overview (see
fig. 3-6).
The permissible water pressure range during operation is de-
pendent on the ROTEX HPSU monobloc compact and the
heating system. The target values and thresholds may only be
set by the heating expert. If the water pressure drops below the
minimum value (set parameter value), it must be increased by
topping up the system (see ROTEX HPSU monobloc compact in-
stallation instructions, chapter entitled "Inspection and mainte-
nance").
3.4.2 Setting the operating mode
The operating mode in which the ROTEX HPSU monobloc com-
pact is to operate is selected using the rotary switch in the

ROTEX HPSU monobloc compact operates according to
the set operating mode.
The current operating mode is indicated by an appropriate
symbol on the standard display.
Operating mode Standby (Stand-by)
The pressure limits for safety shut-off and the target
pressure can be set in the parameter setting on the
"System Configuration"
level.

CAUTION!
A heating system that is not protected against
frost can freeze in the event of frost and thus be
damaged.
●
Add glycol to the heating water circuit (see
installation and maintenance instructions)
●
Alternatively, drain the heating system on the
water side if there is a danger of frost.
●
If the heating system is not drained, the
power supply must be ensured and the
external main switch must remain switched
on if there is a danger of frost.
