Times for luminous heaters, tube heaters and warm air heaters
The submenus of the three heater types are identical:
Minimum running time Minimum time for which the heater must be switched on.
Minimum pause time Time until the heater may be switched on again.
Minimum full load time Minimum time for which the heater must run at full load.
Fan lag time Time for which the fan continues to run after it has been switched off.
These waiting times are displayed in the info bar [section 5.3.3. symbol 6].
Heater switch-on and switch-off thresholds
The switching hysteresis prevents the heater from being constantly switched on or off when the limit value is
reached.
Control output = X% or > X% = heater switches on.
Control output < X% = heater switches off.
The current percentage values of the control output are displayed in the info bar [section 5.3.3] in expert
mode.

Single-stage
One output relay is assigned to the heater [section 7.2].
Switch-on threshold > Switch-off threshold
The status icons "Heater status" + ON/OFF are set [section 5.3.3. symbols 7 + 8].

Two-stage
Two output relays are assigned to the heater [section 7.2].
Relay 1 operates in the same way as for the single-stage heater. Relay 2 switches on the full load, also with
hysteresis.
Full load threshold On > Full load threshold Off > Switch-on threshold > Switch-off threshold
The status icons "Heater status" + ON/OFF/LOW are set [section 5.3.3. symbols 7 + 8].

Modulating
Two output relays are assigned to the heater [section 7.2].
Relay 1 operates in the same way as for the single-stage heater. Relay 2 outputs modulation values to adjust
the heater output.
Switch-on threshold > Switch-off threshold
Modulation start value = X% of the control output corresponds to modulation level #1
The status icons "Heater status" + OFF/#0...#25 are set [section 5.3.3. symbols 7 + 8]
