4.3.10.1 - General

This menu displays the status of the controller outputs. More- over, when the machine is fully stopped (LOFF) the outputs can be activated for manual or automatic tests (the access to the tests is password controlled).

OUTPUTS STATUS & TESTS MENU [2] [3]

ITEM	FORMAT	UNITS	DESCRIPTION
0	b1b2b3		Circuit A compressors, command status
			b1 = compressor A1
	tESt		b2 = compressor A2
	FAIL	-	b3 = compressor A3
	Good		In test mode, the Arrow buttons display 001, 010 and 100 in succession, so as to force the status of the compressor outputs
			in turn. During the test phase, power to the compressor is switched on for 10 seconds only. It is then not possible to restart the
			compressor for a further 30 seconds. When the test is completed the following is displayed:
			- Fail: displayed if the test has failed because the compressor was not started or run in reverse rotation.
			- Good: displayed if test was successful
1 [1]	b1b2b3		Circuit B compressor, dual-circuit units only
			b1 = compressor B1
	tESt		b2 = compressor B2
	FAIL	-	b3 = compressor B3
	Good		In test mode... as above
2	StoP		Two-speed fan status, circuit A
	LOW		Stop = fan is stopped
	HIGH		Low = fan is in low speed
	tESt	-	High = fan is in high speed
3 [1]	StoP		Two-speed fan status, circuit B
	LOW		Stop = fan is stopped
	HIGH		Low = fan is in low speed
	tESt	-	High = fan is in high speed
4 [1]	b1b2	-	Single-speed fan status
			b1 = fan A2
			b2 = fan B2
			Only for dual-circuit units
5 [1]	On		Evaporator water pump #1 command status. Not displayed if the unit does not control a pump.
	OFF		On: pump is running
	tESt		Stop: pump is stopped
	FAIL		Forc: this item is displayed only when the unit is stopped locally (LOFF). selecting this item authorises turning on the
	Good		pump with no delay and for an unlimited length of time. The pump will remain on until any button of the user interface is
	Forc	-	pressed: it is then immediately stopped. If the unit is in CCN control, then the pump status is displayed in turn with "Forc"
			if the pump status if forced through CCN.
			During the test phase, power to the pump is switched on for 10 seconds only. When the test is completed the following is
			displayed:
			- Fail: displayed if the test has failed because the pump was not started
			- Good: displayed if the test was successful
6 [1]	On		Evaporator water pump #2 command status. Not displayed if the unit does not control a secondary pump.
	OFF		On: pump is running
	tESt		Stop: pump is stopped
	FAIL		Forc: this item is displayed only when the unit is stopped locally (LOFF). selecting this item authorises turning on the
	Good		pump with no delay and for an unlimited length of time. The pump will remain on until any button of the user interface is
	Forc	-	pressed: it is then immediately stopped. If the unit is in CCN control, then the pump status is displayed in turn with "Forc"
			if the pump status if forced through CCN.
			During the test phase, ...as above
7	On		Water or air heat exchanger heater command status
	OFF		See sections 5.5 and 5.11
	tESt	-
8	b1b2		Alarm output command status
	tESt	-	b1 = alarm circuit A
			b2 = alarm circuit B
			In test mode, the Arrow buttons display 01 and 10 in succession, so as to force each alarm output status in turn.
9 [1]	On		Boiler command status. Displayed if the unit controls a boiler. See section 5.13.
	OFF
	tESt	-
10 [1]	nnn		Variable fan speed, circuit A. Displayed if the unit controls a variable-speed fan.
	tESt	%
11 [1]	nnn		Variable fan speed, circuit B. Dual-circuits only and if the unit controls a variable-speed fan.
	tESt	%

12 [1]	b1b2
	tESt

4-way reversing cycle valve status. In test mode, the arrow keys successively display 01 and 10, in order to authorise the test for each valve in turn.

b1 = valve circuit A b2 = valve circuit B

This item is only displayed for heat pump units.
