6.6 Viewing a different zone temperature Should the SCB30 be configured to control more than one heating zone, the following instructions enable you to switch zones and view the temperature within that zone.

Temperature within zone

Zone being displayed

If /Pb=1 connect the key selector of a key operated sensor to the contacts Kx-C (with x=1 or 2 or 3 or 4).

The heating zone can be manually started by the key inserted in the zone sensor, and set to:
· AUTO: The controller activates according to the automatic/manual parameter, usually activates according to the timer programs set for the selected zone.
· ON: Timer is excluded in the selected zone, heater/s activate to maintain the comfort set-point SP1
· OFF: timer is excluded in the selected zone, heater/s activate to maintain the frost protection set-point rt

If /Pb=2 the controller does not execute the timer programs or the automatic/manual parameter.
Connect a volt free contact of a BMS to the contacts Kx-C (with x=1, 2, 3, 4).
The heating zone can be manually started by the BMS contact:
· If closed: Heater/s activate to maintain the comfort set-point SP
· If open: Heater/s off, they activate only to maintain the frost protection set-point rt

7. Optimiser Function
Only available when parameter /P5 = Yes

7.1 Optimised Start When the controller is in Auto mode it is possible to select the working period optimisation. Through this function, it is possible to reach the desired temperature at a fixed

time. This will help reduce energy usage.

This is the result of constantly controlling the ambient temperature in every zone, of the set point value (which is set by the user for that specific zone) of the system temperature increase in degrees/hr and the value of the out-
side temperature.

In this way, the system is able to set out and if necessary to revise the pre- start period required to reach the desired temperature. The absence of any connections to external events in defining the starting period erases all possible interferences caused by internal or external climatic changes in the room. In the event of an unexpected increase of the system heating efficiency, due for instance to a different humidity value of the air, the electricity supply will immediately be interrupted until the next analysis of the variables.

The parameters for this function [t0, tr] are set by the manufacturer to standard levels. Please check them with regard to the specific controller.

7.2 Optimised off Through this function, it is possible to maintain the desired temperature during the timer period, but also to avoid excessive temperature in the space when the timer program switches off. This will help reduce energy usage.

During the last t3A*10 minutes of the timed program in progress, the working temperature decreases to SP ­ t3b.

Parameter AL and AH values are the alarm absolute limits of low temperature Lt and high temperature Ht of all zones. They are fixed and do not track the set- point value when it is changed.

AL=LSL (LSL = bottom end of scale). The low temperature alarm is equal to sensor fault alarm E1. AH=LSH (LSH = top end of scale). The low temperature alarm is equal to sensor fault alarm E1.

9. Parameter Menus Overview
To set the parameters of the controller, access one of the following menus:-

P /: Sensor parameters P r: Regulator parameters, set point settings P L: Output parameters P A: Alarm parameters P t: Timer parameters P H: Other parameters

These menus gather the parameters for the relevant function. Inside each menu, only the parameters enabled by the password entered, will be shown.
