1. Description
The Alpha Climatic energy manager is a programmable modulating room thermostat capable of controlling time and temperature for heating
varying the primary flow temperature depending on the room temperature.
The controller also allows remote control of the hot water function and other boiler features.
Connection to the boiler is via a two core cable to the low voltage bus connection for hard wired version or via an integrated RF receiver for
the RF version.
2. Mounting of the Controller
The controller must be mounted in a position where it can not be influenced by direct sunlight, any device which might emit heat, near a door,
window or be obstructed by curtains. It must be installed approximately 1.5m from the floor and any radiators within the same room must not
have thermostatic radiator valves or any other thermostatic control fitted to them.

The mode selection switch (1) has five settings.
a. In this mode the control is switched off but the boiler frost protection is still active.
b. In this mode the control is switched off but provides frost protection for its immediate location.
c. This mode provides hot water only (summer setting).
d. This mode provides hot water and timed and temperature controlled heating (winter setting).
e. This mode is used in conjunction with an air conditioning unit to provide summer cooling control.(Hot Water is also active)
b. Central Heating Temperature setting (8)
The central heating temperature setting adjusts the primary heating water temperature to the user’s requirement. When the dial is turned the
temperature setting is displayed on the screen.
The primary flow temperature might not reach the temperature set by the user when in operation because the programmer will control the
boiler output to give optimum performance to reach the required room temperature setting.

j. Faults Diagnostics and Errors
The Climatic remote control continually controls the functioning of the boiler and signals any anomalies, stating the corresponding error code
on the display.
The error codes are listed in the boiler installation manual.
If a fault occurs it will be displayed as “ERR-XX” where the “XX” represents a number that identifies the code as well as a flashing
symbol.
The climatic also checks its own functioning state, indicating any malfunction.
Code Description
ERR>CM (Climatic Display) Communication error between the Alpha Climatic remote controller or receiver and the boiler.
ERR>TP (Climatic Display) Error in reading the room temperature or value measured off scale (below 0ºC or over 50ºC)
E51 (Boiler display) Communication error between the Alpha Climatic remote controller and receiver. (Climatic RF only)
k. Reset Errors
In the event of a resettable boiler lock out RESET will flash on the display. By pressing and holding the reset button (ref 2 fig 4) for 5
seconds, it is possible to reset the boiler.
It is possible to reset the boiler up to 5 times then one hour must elapse until one more attempts can be made.
l. Reset Climatic Remote Control
By pressing the reset button (ref 4 fig 4) the climatic remote control hardware can be reset without losing the user setting, such as time, date
and timed programmes.

m. Special Functions
By pressing the MENU button, a list of options can be accessed, by pressing the +/- buttons you can scroll through the various options and to
select press OK.
n. Language
Allows the user to choose between Italian and English.
o. Regult (management of regulation parameters)
This allows you to customise the functioning parameters.
CH MIN allows adjustment of the minimum central heating flow temperature. This value is used to calculate the curves used for the external
probe. Values that are too high can cause flow temperatures that are too high on average for room central heating.
OFFSET (regulation constant), constant that can be regulated from -15ºC to +15ºC and which in the presence of the optional external probe
modifies the set flow temperature (see fig 5) set as standard at 0ºC.
NOTE; if the self leaning function is enabled the offset value could be modified automatically.
BUILD (dimension and build inertia), adjustable from 1 to 20, default setting is 10.It establishes the reaction speed of the system depending
on the type of system present.
Example:
AUTO A (self learning), defines the activation of self learning, as per standard set at OFF. This function allows the Climatic remote control to
vary the offset, adapting it to the room in which it is installed.
Value System Type
5 System with little heat inertia e.g. Fan Assisted Radiators
10 System with normal inertia e.g. Standard Radiator system
15 System with high heat inertia e.g. Under-floor Heating

p. Holiday Mode
During winter mode function it is possible to deactivate both the hot water and central heating for a defined number of days (1 to 99). When
the set number of days has past normal function will resume.
When the holiday mode is set a flashing will be displayed and the number of days it is enabled for.
To set the holiday mode press OK then the + button until HOLIDY appears then OK to accept. Off will be displayed and by pressing the +
button the number of days can be set, press OK then ESC once to get to main menu and the symbol and set number of days will flash
at the bottom of the screen.
This function can be deactivated by pressing the button.
In the event of remote telephone activation the Climatic controller will revert back to normal operation omitting the holiday program.
NOTE; the frost protection function is still active during holiday mode.
q. Legion (anti-Legionella function)
The anti-Legionella function raises the temperature of the hot water storage cylinder to the maximum boiler set temperature for 20 minutes to
kill Legionella bacteria.
It is possible to set this function once a day at 2am (ON 24H), every Monday at 2am (ON 7 DAYS) or deactivate it (OFF standard function).
NOTE; this function must only be activated when a cylinder is present and a thermostatically controlled blending valve should be fitted to the
cylinder hot water outlet.
