(1) the unit of measurement depends on parameter P21
(2) if parameter P9 is set at 4 and the CFG parameter is set at 0, 1, 2 or 3 (or if the CFG parameter is set at 8), the unit of measurement will depend on parameter P22
(3) the unit of measurement depends on parameter P22
(4) set the parameters relative to the regulators appropriately after modification of parameters P21 and/or P22
(5) if the parameter P01 is set at 0, 1 or 2 and the parameter P21 is set at 2, the device will operate as if parameter P21 is set at 0
(6) if the parameter P02 is set at 0, 1 or 2 and the parameter P22 is set at 2, the device will operate as if parameter P22 is set at 0
(7) if the parameter P01 is not set at the same value as parameter P02, the instrument will operate as if the parameter P9 is set at 0
(8) the parameter also has effect after a power cut, which occurs when the device is on
(9) the time established with the parameter is counted also when the device is off (stand-by state)
(10) the protections are respected at switch-on (parameters C0, C1 and C11)
(11) a switch-on sequence could be the following:
K1 off - K2 off - K3 off - K4 off
K1 on - K2 off - K3 off - K4 off
K1 on - K2 on - K3 off - K4 off
K1 on - K2 off - K3 on - K4 off
K1 on - K2 on - K3 on - K4 on
(12) a switch-on sequence could be the following:
K1 off - K2 off - K3 off - K4 off
K1 on - K2 on - K3 off - K4 off
K1 on - K2 off - K3 off - K4 off
K1 on - K2 off - K3 on - K4 on
K1 on - K2 off - K3 on - K4 off
(13) the magnitude associated to the minimum and maximum alarms is that detected by probe 1
(14) if the CFG parameter is set at 7 and the parameter A2 is set at 1, the minimum alarm will be relative to the work set-point SP1
(15) if the CFG parameter is set at 7 and the parameter A5 is set at 1, the maximum alarm will be relative to the work set-point SP2.
2 = ACTIVATION OF MANUAL RESTORE EXTERNAL ALARM - on expiry of time i2
the relays used for regulation will be forced into the state established with
parameter C5.
Any relays for signalling alarms and errors (CFG = 3) will be on, the display will
show the “iSd2” code flashing and the buzzer will be activated. The cause of the
alarm must disappear and then the
and keys must be pressed for 1 s in
order for the device to restore normal operation
3 = DEVICE SWITCH-ON/OFF - on expiry of time C3, the device will be off (stand-by
state) and the display will show the magnitude established with parameter P5 for
½ s every 4 s (while the input remains active)
4 = ACTIVATION OF THE WORK PROGRAM FUNCTION - if r23 = 2, the Work Program
function is activated (see paragraph 4.5)
type of digital input 2 contact
0 = normally open (input active with closed contact)
1 = normally closed (input active with open contact)
state of he relays used for regulation during the external alarm delay from digital
input 1 (codes “id1” and “iSd1”) and external alarm from digital input 2 (codes “id2”
and “iSd2”)
0 = the relays will be off
1 = the relays will be switched on (10)
2 = the heating mode operation relays will be off
3 = the cooling mode operation relays will be off
DIGITAL OUTPUTS
polarity of the relays for signalling alarms and errors
0 = off during normal operation and on during an alarm and an error
1 = on during normal operation and off during an alarm and an error

silencing of buzzer
1 = YES
enabling the buzzer
1 = YES

0 = cooling mode operation (see paragraph 4.2.1)
1 = heating mode operation (see paragraph 4.2.2)
2 = neutral area operation (see paragraph 4.2.3)
3 = neutral area operation with alarm relay (see paragraph 4.2.4)
4 = operating in cooling or heating mode from digital input 1 (see paragraph 4.2.5)
5 = operating in cooling mode with Energy Saving function from digital input 1 (see
paragraph 4.2.6)
6 = operating in heating mode with Energy Saving function from digital input 1 (see
paragraph 4.2.7)
7 = operation for cooling and heating mode with two independent work set-points
(see paragraph 4.2.8)
8 = operation with two independent neutral areas (see paragraph 4.2.9)
9 = operating in cooling or heating mode from probe 2 (see paragraph 4.2.10)
