Eng.
• Boiler temperature controller with 3-wire modulating control
• Communication systems :
– C-Bus
for Telemanagement
– C-Ring
for exchange data of common interest between local controllers
• Power supply 230 V~ , DIN rail mounting
1. APPLICATION
DTC 628 controller is designed for temperature control of a boiler with three-wire modulating burner (common -
increase - decrease).
2. FUNCTIONS
The principal functions of DTC 628 are:
• The control of the boiler temperature can be :
– Compensated / Fixed Point :
– Compensated: variable in relation to outside temperature.
Use the desired room temperatures: Normal 1...5; Setback 1-2, Frost Protection.
– Fixed Point: at fixed point.
Use the desired boiler temperatures: Fixed Point 1and Fixed Point 2.
– Zones: variable in relation to temperature requested by controllers of these zones connected in C-Ring.
• Control 3-wire modulating burner (common - increase - decrease).
• On-Off control of boiler shut-off valve
• On-Off control boiler pump or manifold or heating plant..
• Timed programming with seven 24hour and two 7day programmes.
• Programming with dates: 25 annual periods; one special period; heating season.
• Automatic switching British Summer Time (BST)/Greenwich Mean Time (GMT).
• Eco Off function: boiler off when outside temperature exceeds a pre-set value.
• Remote control for changing programme in use.
• Four On-Off inputs for : - 3 general alarms
- 1 alarm for burner lockout with simultaneous total exclusion of the boiler with locked-
out burner (closure shut-off valve and pump idle)
• 1 input measurement flue gases temperature.
• Alarms for short or open detector circuits and defective controller..
• C-Ring connection for local exchange of data with other controllers.
• C-Bus connection for transmitting data to local PCs or remote Telemanagement PC.
• Simulation of operation for testing electrical connections at commissioning.
