DIM A-2BT ERP Installation diagram (1 direct zone and 2 

mixed zones).

 Key:

 S20-1  -  Direct zone 1 room thermostat (RT)

 S20-2  -  Mixed zone 2 room thermostat (RT)

 S20-3  -  Mixed zone 3 room thermostat (RT)

 

1  -  External probe (optional)

  2 - Boiler

 

3  -  Comando Amico Remoto

V2

 remote control (optional)

  RZ1  -  Direct zone 1 return

  RZ2  -  Mixed zone 2 return

  RZ3  -  Mixed zone 3 return

 MZ2  -  Mixed zone 2 flow

 MZ3  -  Mixed zone 3 flow

 MZ1  -  Direct zone 1 flow

Factory settings define zone 2 as the main zone.

(See Fig. 20 for electrical connection and Fig. 21 for zones control unit 

setting)

1.7  COMMISSIONING THE DEVICE.

System filling.

 Once the device is connected, fill the system via 

the boiler filling valve.

Filling is performed at low speed to ensure the release of air bub-

bles in the water via the boiler and central heating system vents 

and the distribution manifold (if any).

Close radiator vent valves when only water escapes from them.

Close the filling cock when the boiler pressure gauge indicates 

approx. 1.2 bar.

IMPORTANT:

 during these operations, start the circulation 

pumps by acting on the main switch positioned on the boiler 

control panel after having activated the T.A. devices relating to 

the various zones. 

(Only for DIM H-LT and H-2LT ERP).

Act manually on the 3-way mixing vale using the relevant lever 

on the electric actuator, keeping the same opening in order to 

de-aerate the system and, if necessary, control the correct oper-

ating pressure.

Once these operations are complete, make sure that the lever on 

the electric actuator is free from the manual lock position.

1.8  CIRCULATION PUMP.

The pump is ideal for the requirements of each central heating 

system in a domestic and residential environment. In fact, the 

pump is equipped with electronic control that allows you to set 

advanced functions.

Adjustments.

 Turn the selector and position it on the desired 

curve to adjust the circulator pump.

Program P (1 lower 2 upper ) (ΔP-V) - Proportional curve

 

(green LED).

 This allows the pressure level (head) to be pro-

portionally reduced as the system heat demand decreases (flow 

rate reduction). Thanks to this function, the electric power con-

sumption of the circulator pump is reduced further: the energy 

(power) used by the pump decreases according to the pressure 

level and flow rate. With this setting, the pump guarantees 

optimal performance in most heating systems, thereby being 

particularly suitable in single-pipe and two-pipe installations. 

Any noise originating from the water flow in the pipes, valves and 

radiators is eliminated by reducing the head. Optimal conditions 

for thermal comfort and acoustic well-being.

- Programs C (3 lower 4 upper ) (ΔP-C) - Constant curve (or-

ange LED).

 The circulator pump maintains the pressure level 

(head) constant as the system heat demand decreases (flow rate 

reduction). With these settings, the circulator pump is suitable 

for all floor systems where all the circuits must be balanced for 

the same drop in head.
