Start-up with RAMSES 850 top2 OT • The OT box RAMSES top2 can be adapted for the particular heating system (5 systems) by setting different applications. After connection, the messages follow in the display (see image). • The selection “Weather or room-dependent control” is made via the sensor connection. If an ambient temperature sensor is connected, it will be automatically detected and weather-dependent control will be carried out.
Set TSP parameters (Transparent Slave Parameters) 0: Domestic hot water circulation pump only runs when temperature-controlled 0–99: Domestic hot water circulation pump via ΔT on, Value is the maximum runtime in s 10 Pump protection time (0 .. 11 pm, default 12) 11 Pump protection duration in s (0…99, default 15, 0 = no pump protection) 12 ΔT for sequence control (5 ... 25, default 15) resolution 0.1 K 13 ΔT1 for pump switch heater 1 (5 ..
Systems/Applications 1–5 which are linked via the OpenTherm bus. RAMSES 850 top2 OT as well as both boxes are linked with one another via the OpenTherm bus. The centre box must be linked to the 0–10 V (terminal 15 - 15) input with a wire bridge. With the RAMSES 856 top2 OT an additional OT box (standard box 9070712) will be required for this system. • For the systems or applications 1-4 the OT-Box RAMSES top2 OT is required. The OpenTherm bus links RAMSES 850 top2 OT with the OT box RAMSES top2 OT.

System 3 Heizkörper System 3 consists of: • Burner • Heating circuit without mixer • 2. Heater (e.g. solid fuel boiler) • Buffer storage • Water storage tank • Domestic hot water circulation pump (Domestic hot water return pump) The individual functions are activated by connecting the appropriate sensor, i.e. the domestic hot water program is only executed when the domestic hot water temperature sensor is connected.
System 4 System 4 consists of: • Burner • Heating circuit with mixer • 2. Heater (e.g. solid fuel boiler) • Buffer storage • Water storage tank • Domestic hot water circulation pump (Domestic hot water return pump) The individual functions are activated by connecting the appropriate sensor, i.e. the domestic hot water program is only executed when the domestic hot water temperature sensor is connected.
System 5 – comfort box System 5 consists of: • Burner • Heating circuit 1 with mixer • Heating circuit 2 with mixer • 2. Heater (e.g. solid fuel boiler) • Buffer storage • Water storage tank • Domestic hot water circulation pump (Domestic hot water return pump) The Comfort box consists of RAMSES 850 top2 OT and 2 standard boxes (centre box and end box). With it additional inputs/outputs are available for the connection of pumps, etc. Standard box (without RAMSES 850 top2 OT) can be obtained from Theben.

2 Switch chimney sweep function on/off Connect USB/GSM modem Press button on the OT-Box RAMSES top2 OT x 1. The LED lights up. The chimney sweep function (burner + pump, for measurement of emissions by the chimney sweep) is on (full load). Press button again; the function is switched off. If not switched off manually the chimney sweeping function ends automatically after 30 mins. In the SETTINGS menu the additional sub-menu PIN CODE appears.
Error messages When you receive PIN:xxxx Set:xx,x via SMS, Replace the x with the correct PIN code/desired temperature. If an error occurs during the adjustment, error codes appear in the RAMSES 850 top2 OT display. Error codes 20-28 originate with a sensor error. 2.
