This device is a elay module designed to dive loads (moe pecisely, electo-themal valves o ciculatos) via adio in home o office heating/cooling systems. It featues 8 independent channels, each of which can be associated with an independent tansmitte (adio themostat o chonostat). This system is undoubtedly the best solution fo all buildings in which wies cannot be laid between themostats and the
Each themostat o chonostat tansmitte emits “adio commands” towad the active antenna accoding to the heating and cooling euiements of the oom whee the themostat is located in and accoding to the pogammed setpoint. These commands ae then eceived by the active antenna, installed in a suitable position in the oom whee
The active antenna then tansmits digital data to the elay module via a data cable so that only the elay associated with the tansmitte concened will switch on o off accoding to need. Each elay output can be connected to a valve that will contol the flow of hot/cold wate in the heating/cooling unit pesent in the oom. In addition to the channel outputs, the device featues an “auxiliay” output, which is activated each time at least one of the actuato outputs (channels 1-2: see also “Pump Opeation”) is switched on. While it is opeating, the elay module continuously monitos the status of each

The use must take account of the enegy consumption of
loads and make sue that the extenal powe souce is capable of supplying the total powe necessay in the wost possible situation (i.e. when all loads ae switched on). Fo example, if you use 2 actuatos each euiing 3W at 24V~, it will be necessay to povide an extenal tansfome with a 24V~/6W output (3W x 2 actuatos). A safety magin of at least +10% is stongly ecommended: in the peceding example, this would mean using at least a 8W tansfome. The slow-blow potection fuse supplied,
, has a tip value of 2A, which is suitable fo 4 standad 230V~ actuatos. If you need to connect a lage numbe of actuatos o 24 V~ actuatos, you should eplace fuse
with one having a highe ated tip cuent. The fuse should be sized so as to withstand the inush cuent of the actuato; in case of need, ask you local etaile fo futhe infomation. Teminals 7 and 8 ae the auxiliay output teminals fo

The 2 channels elay module can also be connected in a chain fashion to a 8 channels elay module so that all the units of the chain will use the same active antenna. In case the unit is to be connected in a chain fashion, an inteconnection cable must be plugged between the “SIGNAL OUT” socket of a 8 channels elay module and the “SIGNAL IN” socket of the 2 channels elay module. See the wiing examples in Fig. 5 and Fig. 6. The module must be the last unit in the chain since it does not have a “SIGNAL OUT” socket connecto on the boad.

If the system uses fewe than two themostats and theefoe does not use all of the outputs, it is impotant to keep the unused channel “inactive” by not assigning it an addess code.

The elay of the auxiliay output is activated each time at least one actuato output is switched on. If the “shae auxiliay output” option is enabled (see paagaph on “DIP-switch options”) the elay will be contolled accoding to the status of the channels of all modules connected in cascade to one anothe. If the option is disabled, the elay will be activated based solely on the status of the outputs of the module the elay itself belongs to. It is possible to set a delay in the on/off switching of the auxiliay output. The
delay may be set in the ange of 0 to 7 minutes by adjusting the timme indicated by in Figue 2. This will pemit the output to contol a pump, which will wait fo the electo-themal actuatos to open befoe stating to ciculate wate and continue afte all actuatos have been switched off, until they ae completely closed.

This function allows the tempeatue in the oom whee the themostat is installed to be egulated accoding to two setpoints: comfot and economy. The comfot setpoint coesponds to the tempeatue set on the knob, wheeas the economy setpoint is eual to the comfot tempeatue minus a fixed eduction value in the heating mode (in the cooling mode Tcomfot + fixed eduction value). The elay module has 2 timmes, indicated by in Figue 2, by means of which it is possible to adjust the fixed eduction value
Each timme allows you to set the amount of the tempeatue eduction fo the elevant channel: timme SB1 sets the eduction on channel 1 and timme SB2 sets the
The economy mode can be activated by the extenal “Economy” input via an oveide command o contolled by an associated chonostat. The device pemits one o moe themostat-contolled outputs to be associated with the output of a chonostat, so that the associated channels will eceive fom the chonostat an indication as to the time of day and infomation about which setpoint – comfot o
economy – should be used to egulate the oom tempeatue. The OFF o antifeeze status is likewise eceived by the
If the chonostat is cuently set in the comfot mode, the associated themostats will abide by the setpoint set on thei espective knobs; if, on the othe hand, the chonostat is cuently set in the economy mode the associated themostats will apply the tempeatue eduction as descibed above. Similaly, if the chonostat is off with the antifeeze function set on 5°C, the associated themostats will likewise be set on an antifeeze tempeatue of 5°C. The themostats can have a selecto that allows them to be set in the comfot o economy mode accoding to the time schedule of the associated chonostat, o to oveide the latte so as to emain always set in the comfot mode o always off.

When the “Heating/Cooling selection via extenal input” option is enabled, the extenal Heating/Cooling contact will detemine the opeating mode fo all themostat-contolled channels of the module. See the paagaph on “

The elay module is factoy configued (DIP-switch 4 down) so that that the Heating/Cooling status of each channel will be detemined by the setting of the associated themostat
Howeve, if a chonostat is pesent in the system, it will oveide the themostat settings and impose its own Heating/Cooling status on all themostat-contolled channels, including those of othe modules connected in cascade to the
This makes it possible to change ove the mode selection easily by means of a single device (chonostat) without
If thee is moe than one chonostat in the system, the one contolling the lowest channel (in the module closest to the antenna, in the event of a numbe of cascade-connected modules) will oveide the othes in detemining the Heating/
The Heating/Cooling status of a chonostat can neve be changed via the elay module: it must always be adjusted manually. The options pemitting a global Heating/Cooling changeove apply only fo the channels contolled by
If the elay module is configued so that the Heating/Cooling status is detemined by an extenal input (DIP-switch 4 up), the themostat-contolled channels will take on the status defined by the extenal contact. Howeve, the module cannot change the Heating/Cooling status of any channels contolled
In cases whee a chonostat is pesent in the system, it is not convenient to use the “Heating/Cooling selection via extenal input” option since you can change the Heating/Cooling setting of all themostat-contolled channels simply
The status of the extenal Heating/Cooling input is
Theefoe, it is not necessay to connect the inputs of seveal modules in paallel: it is sufficient to connect the switch to one module in the chain in ode to change the
If a themostat-contolled channel has been associated with a chonostat, the channel will always take on the Heating/Cooling status of the associated chonostat, iespective of

To the “Global standby” input it is possible to connect a contact which, when closed, will cause all channels of the
Even the channels contolled by a chonostat will be switched
If the system is opeating in the heating mode (as detemined by the Heating/Cooling status of a chonostat o an extenal input o, in the absence of the latte, by the themostat settings), the antifeeze function will be activated with a fixed setpoint of 6.0°C to pevent the tempeatue within
When closed, the extenal “Economy” input will cause all
themostat-contolled outputs to egulate tempeatue at the educed economy setpoint. See paagaph on “Associating
By connecting an extenal clock switch to the “Economy” input you can educe the tempeatue setting duing the
This poduct euies no paticula maintenance. Once the system is installed and opeational, it is good pactice to check peiodically that the uality of the signal eceived is good. If the signal is weak o absent on one o moe channels, the coesponding LEDs will blink: this could occu if the batteies ae low. If the fuse has blown (see “Toubleshooting”), disconnect the powe supply and check the electical system and valves used. Replace with a fuse of
