Occupancy is detected by the occupancy sensor, this signal will be used by the controller
to enable the fan and controls, the period for which it will work after detecting an occupant
is set using the Occupancy Timer; "Occupncy Tmr xxm" change steps using the +/-
buttons. 5 to 60 minutes in 5-minute steps.
PIR Contact normally open or normally closed setting facility "PIR Contact – NC or NO"
Default N/O, closing to indicate occupancy
Fan Run On timer is the time for which the controller will allow the fan to run after the unit
has been switched off; this allows dissipation of residual heat on the heat exchanger. "Fan
Runon xxm" change steps using the +/- buttons. 0 to 15 minutes in 1-minute steps.
(Default 3 minutes)
BMS Contact, normally open or normally closed setting facility. "BMS Contact – NC or
NO" Default N/O, closing to disable unit.
BMS Summer/Winter input, if enabled (ENA) the PIR contact input becomes a
summer/winter mode switch the "BMS S/W ip – ENA or DIS" Default DIS (disabled). The
input is open for Summer mode and closed for Winter mode.
BMS 0-10v fan input, if enabled (ENA) the fan speed is taken from a 0-10v signal on the
fan speed analogue input (see 3.1). The fan speeds are set as follows...
Fan Off:
Fan speed 1: 3 volts (2v-4v)
Fan speed 2: 5 volts (4v-6v)
Fan speed 3: 7 volts (6v-8v)
Fan speed 4: 9 volts (8v-10v)
P I D terms
"P Factor x" change steps using the +/- buttons. Change the Proportional value as
instructed by factory. (Default 75 for electric and 30 for water)
"I Factor x" change steps using the +/- buttons. Change the Integral value as
instructed by factory. (Default 9 for electric and 4 for water)
"D Factor x" change steps using the +/- buttons. Change the Differential value to suit.
(Default 10 for electric and 0 for water)
PWM Period adjustment, "PWM P fast or slow". Default slow 12.75 seconds period.
Actuator travel time, hot water valve actuator travel time in seconds (default 150) used
when DIP switch 4 is on, water heating system.
Lock the user interface, "Lock UI – YES or NO", once set to yes the user cannot change
any settings and pressing the buttons has no effect. The display shows Off coil
temperature (C),
(Summer/Winter/Auto). The summer/winter setting and fan speed cannot be changed
without entering engineer mode (see 4.4.6).
