With its unique synthesis of proven technology and innovative With its unique synthesis of proven technology and innovative features, the Vitocrossal 300, CA3B takes a bold step forward while features, the Vitocrossal 300, CA3B takes a bold step forward while retaining the superior Viessmann quality you know and trust. retaining the superior Viessmann quality you know and trust.

The Vitocrossal 300, CA3B offers gas-fired condensing technology with fully-modulating pre-mix cylinder burner.

Viessmann technology from top to bottom Our fully-modulating pre-mix cylinder burners feature a wide modulation and combined burner turndown ratio of up to 15:1. This matches the load to provide clean, quiet and environmentally friendly operation. The burners come fully assembled and installed for ease of commissioning.

The SA240 stainless steel Inox-Lamellar heat exchanger surface provides maximum heat extraction while maintaining a compact size. Its smooth, corrosion resistant surfaces allow condensate to simply run off, creating a “self-cleaning” process that ensures continuous condensing efficiency, reduced maintenance costs, and longevity. The 160 psi pressure rating allows for this unit to be installed in almost any building.

With the Vitocrossal 300, CA3B, Viessmann offers outstanding thermal efficiencies over 96% and delivers exceptional performance and reliability at an attractive price.

Progressive design features The Vitocrossal 300, CA3B can operate with a low inlet gas pressure of only 4 inches of water column (NG), eliminating the need for gas boosters. With low water pressure drop, the heat exchangers are ideal for variable primary systems and eliminate the need for a dedicated boiler pump. The boiler’s large water content reduces wasteful burner cycling, thereby increasing system efficiency and overall durability.

A versatile solution The Vitocrossal 300, CA3B offers a solution for almost every ap-plication, such as multiple venting options and seamless integra-tion into building management systems (BMS). The Vitocrossal 300, CA3B comes fully assembled, which makes it easy to ins-tall, even older buildings with narrow entrances or small mecha-nical rooms. Suitable for high altitude operation of up to 10,000 feet, the sky‘s the limit for the Vitocrossal 300, CA3B.

Dual fuel: Switch from natural gas (NG) to LP Dual fuel is a feature that maintains normal operation in critical care applications, such as nursing homes, hospitals, educational institutions, industrial operations, and more. The Vitocrossal 300, CA3B provides the ability to easily switch from natural gas (NG) to LP at the simple turn of a key (must be pre-ordered).

User-friendly control system The Vitotronic 300, GW6C control system is an advanced digital boiler and system control with outdoor reset function that ensures reliable, efficient performance of the entire heating system. The Vitotronic 300, GW6C will modulate stages and rotate burners to meet the heating system‘s load. The standard control package will regulate supply water temperature for one high temperature circuit, two mixing valve circuits, and one DHW circuit.

Multiple-boiler systems The built-in Vitotronic 300, GW6C cascade control system is simple to use, as it automatically stages burners and rotates boilers to match heating loads up to 12,000 MBH. For larger systems, Viessmann also offers custom boiler controls with virtually unlimited capacities and additional options such as real time system loading, VFD pump outputs, BTU metering, and efficiency trending.

SAFETY STANDARDS AND PROTECTION

� Enclosure: Class 2, IP44 (equivalent to NEMA Type 2) � UL Listed to UL 778; UL 1004-1, 1004-7; and UL 60730-1 � cUL Listed to C22.2 #108 � Electronically Thermally Protected (Integrated Motor Protection) � Motor Insulation Class: F � Stainless steel models are CSA Certified for NSF/ANSI 61 that product contains less than 0.25% lead content by weight on wetted surface. certified.

STANDARD OPERATING MODES

CONSTANT SPEED

The pump maintains a constant speed at any flow rate. The desired speed is set on the interface panel of the pump.

CONSTANT PRESSURE (Δp-c)

The pump maintains a constant differential pressure at any flow demand until the maximum speed is reached. The desired head of the pump can be set via user interface. Recommended for use in systems with small or constant pressure losses.

PROPORTIONAL PRESSURE (Δp-v)

The differential pressure continuously increases or deceases based on the flow demand. The set point head can be set on the pump user interface. Use for systems with large pressure losses.

NIGHT MODE

The pump will automatically reduce speed when there is an abrupt change in fluid temperature. The change in fluid temperature is from a boiler operating in night time setback mode. The built-in temperature sensor is used. (Fixed Speed, Constant Pressure, Proportional Pressure)

TEMPERATURE DEPENDENT OPERATING MODES

SET POINT TEMPERATURE (Δp-T)

The nominal differential pressure set point is modified based on the fluid temperature.Uses the built-in temperature sensor.

SET POINT TEMPERTURE (T)

The pump maintains a constant temperature in a system, such as domestic hot water system or a single temperature heating system.

Uses the built-in temperature sensor.

DIFFERENTIAL TEMPERTURE (ΔT)

The pump maintains a constant differential temperature between the built-in and external temperature sensors.

INPUT SIGNALS

� One 0-10V (Analog): Speed Control by external controller � One 4-20mA (Analog): Connection with an external differential pressure sensor for pressure control mode (two differential pressure sensor ranges: 0-15 and 0-30 PSIG) on single phase models.

● Two absolute pressure sensors 4-20mA (Analog) input for three phase models.

� One external temperature sensor input for Differential Temp operating mode.

Sensor Type: KTY82, P/N: 104502

� One built-in temperature sensor for Set Point Temp and Differential-Temp operating mode.

REMOTE BUILDING MANAGEMENT SYSTEM CAPABILITIES

� The pump can be monitored or controlled by a signal from BMS (Building Management System). Built-in protocols are BACnet and Modbus. Direct connection to a PC is available.

� An optional wireless module can be added to create a short range wireless field for remote connection to the pump. An internet browser can be used to program the advanced settings. Module P/N: 104500

START/STOP CONNECTIONS: Connect to external dry contact relay or use with a thermostat.

OUTPUT RELAY(single phase): Normally Open Dry Contact Relay for Fault Mode indication.

OUTPUT RELAYS (three phase): Two Normally Open Dry Contact Relays for Fault Mode and Run indication.
