Range
WKG.SP
WORKING SETPOINT
is the active setpoint value and appears when the
controller is in Manual mode. It may be derived from SP1 or SP2, or, if the
controller is ramping (see SP.RAT), it is the current ramp value.
SP.HI to SP.LO
WRK.OP
WORKING OUTPUT
is the output from the controller expressed as a percentage
of full output. It appears when the controller is in Auto mode.
In a motorised valve controller (option VC or VP) this is the ‘inferred’ position of
the valve
For a time proportioning output, 50% = relay or logic output on or off for equal
lengths of time.
For On/Off control: OFF = <1%. ON = >1%

SP.HI
SETPOINT HIGH
High setpoint limit applied to SP1 and SP2.
SP.LO
SETPOINT LOW
Low setpoint limit applied to SP1 and SP2
Alterable between range limits
By default the remote setpoint is scaled between SP.HI and SP.LO. Two further parameters (REM.HI and REM.LO) are
available in access level 3 to limit the Remote SP range if required. See section 10.1.
SP1
SETPOINT 1
allows control setpoint 1 value to be adjusted
Alterable: SP.HI to SP.LO
SP2
SETPOINT 2
allows control setpoint 2 value to be adjusted
Alterable: SP.HI to SP.LO
SP.RAT
SETPOINT RATE LIMIT
Rate of change of setpoint value.
OFF to 3000 display units per
minute

TIMER CONFIGURATION
Configures the timer type:- Dwell, Delay, Soft Start or
none. The timer type can only be changed when the timer is reset.
The Programmer option only appears if the programmer has been ordered.

THRES
TIMER START THRESHOLD
The timer starts timing when the temperature is
within this threshold of the setpoint. This provides a guaranteed soak
temperature. The threshold can be set to OFF in which case it is ignored and the
timing starts immediately.
If a setpoint ramping is set, then the ramp completes before the timer starts.

TIMER END TYPE
This determines the behaviour of the timer when it has timed

SS.PWR
SOFT START POWER LIMIT
This parameter only appears if the timer
configuration is set to
sfst
(Softstart). It sets a power limit which is applied
until the measured temperature reaches a threshold value
(SS.SP)
or the set
time
(DWELL)
has elapsed. The timer starts automatically on power up.
