Intelligent Control underfloor heating zone schedule

The following Zone Schedule is an example of the 'as fitted' zone schedule which will be found on the 'as fitted' wiring diagram.  It is to be used in conjunction with the CAD pipe layout drawing.  You will see that it exactly ties up with the sequence of the individual pipe circuits 'as fitted' back to the manifold(s).  For ease of understanding, the sequence of the controllable areas are numbered from left to right on the manifold(s).  Below the exampled zone schedule, there is a brief description of each of the headings.  The most important piece of information that the zone schedule gives is which channel number to set each room sensor to.  This is normally done at the commissioning stage.

ZONE SCHEDULE
ROOM NAME	OUTPUT NUMBER	MODULE TYPE	SENSOR TYPE	SET TO CHANNEL	USE
	1	WLM 2FS	WLTA	1	1 ACTUATOR
	2	WLM 2FS	WLCT	2	2 ACTUATOR
	3	WLM 2FS	WLTD	3
	4	WLM 2FS	WLCT	4
	5	WLM 2FS	WLTA	5
	6	WLM 2FS	WLTA	6
	7	WLM 2FS	WLTD	7
	8	WLM 2FS	WLCT	8
	9	2 WLM 1AO	WLTA	9
	10	2 WLM 1AO	WLTA	10
	11	2 WLM 1AO	WLTD	11
	12	2 WLM 1AO	WLTA	12
	13	2 WLM 1AO	WLTA	13
	14	2 WLM 1AO	WLTA	14

ROOM NAME - Description of the room allocated to that output.

OUTPUT NUMBER - Relates to the output number serving the thermal actuator(s).

MODULE TYPE - Describes which module the output comes from.

SENSOR TYPE - Describes what type of sensor is allocated to that room.

SET TO CHANNEL - Instructs what channel number to set inside the sensor.

USE - States how many actuators are connected to that output.

Points to note:

• More than one actuator can be connected to the same output.  This happens in larger areas that have two or more pipe circuits.
  
  
• In large areas two or more sensors may be specified. These sensors will be set to the same output number, the controller will take an average of the measurements and control the output accordingly.
  
  
• You may also have two separate rooms that have also been averaged. This will be apparent in the zone schedule; two separate areas will have the same 'set to channel' number and the same 'output number'.
  
  
• Inside each sensor there is a setting pot which is numbered 0 to 9 and A to F. 1 to 9 on the pot corresponds to outputs 1 to 9 and A to E corresponds to outputs 10 to 14.  Make sure that the sensor is set to the correct output number.
  
  
• Position 0 on the sensor is used for any clock sensor which is situated in a central position, is not sensing its own zone, but is being used for time and temperature settings of other zones. Position F is not used.
